...Lab #4: Kinematics - Velocity and Acceleration Introduction: The purpose of this lab is to discover and understand the relationships between position, velocity, and acceleration. Additionally, constant/uniform acceleration due to the force of gravity will be examined to find possible mathematical relationships to position and velocity. Velocity and acceleration are changes in position and velocity, respectively, with regards to time. This change can be shown mathematically in calculus derivatives: EQ 1. EQ 2. As dt decreases in value, the instantaneous velocity and acceleration can also be found. Furthermore, if constant acceleration is established, two basic relations between distance, velocity, and the constant acceleration can be found: EQ 3. EQ 4. In any environment near Earth, the acceleration in the vertical direction is constant at a value of g=9.8m/s2 towards the center of Earth or often written as g=-9.8m/s2. In such an environment there is no natural acceleration in the horizontal direction, thus the horizontal motion is analyzed independently of the vertical motion. Thus it can be established that the general form of a position curve for a projectile would follow an inverse parabola shape and the maximum height occurs when vertical velocity is zero. By calculus derivation, it can also be found that the velocity graph would display a linear line with a negative slope. Procedure: This lab consists of two separate but related experiments...

...Velocity Cellular: Trueblood Case 09-1 Case Study: Velocity Cellular Case Study: Velocity Cellular Revenue Recognition in a Multiple-Element Arrangement Velocity Cellular Services is planning the rollout of a new prepaid phone service called Power Starterpack. Using the current, relevant accounting guidance, determine and support the appropriate method for recognizing revenue for this new product. Power Starterpack Details Velocity Cellular sells the Power Starterpack for $200. The Power Starterpack consists of two elements: a new activation card and a prepaid voucher for $50 worth of airtime. The new activation card allows the subscriber’s cellular phone to function and gives the subscriber additional features not available with the old activation card. Activation cards can be purchased separately from Velocity. Identical activation cards can be purchased from other vendors. The $50 prepaid airtime voucher must be used within 360 days or the remaining value is forfeited. If there is no activity for seven consecutive months, the subscriber’s account is closed and the phone number is deactivated. No refunds are given and the subscriber has no general rights of return for the Power Starterpack. Are the Deliverables Considered Separate Units of Accounting? Velocity Cellular adopted ASU 2009-13, “Revenue Arrangements with Multiple Deliverables” in the current fiscal year.

...605-10-25-1: Revenue and Gains 25-1 The recognition of revenue and gains of an entity during a period involves consideration of the following two factors, with sometimes one and sometimes the other being the more important consideration: • a. Being realized or realizable. Revenue and gains generally are not recognized until realized or realizable. Paragraph 83(a) of FASB Concepts Statement No. 5, Recognition and Measurement in Financial Statements of Business Enterprises, states that revenue and gains are realized when products (goods or services), merchandise, or other assets are exchanged for cash or claims to cash. That paragraph states that revenue and gains are realizable when related assets received or held are readily convertible to known amounts of cash or claims to cash. • b. Being earned. Paragraph 83(b) of FASB Concepts Statement No. 5, Recognition and Measurement in Financial Statements of Business Enterprises, states that revenue is not recognized until earned. That paragraph states that an entity's revenue-earning activities involve delivering or producing goods, rendering services, or other activities that constitute its ongoing major or central operations, and revenues are considered to have been earned when the entity has substantially accomplished what it must do to be entitled to the benefits represented by the revenues. That paragraph states that gains commonly result from transactions and other events that involve no earning process, and for recognizing...

...on the body. It is the study of the geometry of motion without consideration of the causes of motion. Kinematics deals only with relationships among the position, velocity, acceleration, and time. Kinetics deals with both forces and motion. 2. PARTICLES AND RIGID BODIES Bodies in motion can be considered particles if rotation is absent or insignificant. Particles do not possess rotational kinetic energy. All parts of a particle have the same instantaneous displacement, velocity, and acceleration. A rigid body does not deform when loaded and can be considered as a combination of two or more particles that remain at a fixed, finite distance from each other. 3. COORDINATE SYSTEMS The position of a particle is specified with reference to a coordinate system. A coordinate can represent a position along an axis, as in the rectangular coordinate system or it can represent an angle, as in the polar, cylindrical, and spherical coordinate systems. In general, the number of degrees of freedom is equal to the number of coordinates required to completely specify the state of an object. If each of the coordinates is independent of the others, the coordinates are shown as holonomic coordinates. 4. CONVENTIONS OF REPRESENTATION For a given particle, position, velocity, and acceleration can be specified in three primary forms: vector form, rectangular coordinate form, and unit vector form. • The rectangular coordinate...

Explain your answer, and state why this question is an exercise in careful reading as well as in Physics. The acceleration is 0. There is no change of velocity in those 100 seconds time interval. The word you have to pay attention to is “steady” that is why is can exercise in careful reading and in Physics because you would try to do the math but at the end the answer would be wrong because the car never accelerated. * Problems 1,5,8 and 10 1.

Abstract This paper presents solutions for one requirement of autonomous characters in animation and games: the ability to navigate around their world in a life-like and improvisational manner. These “steering behaviors” are largely independent of the particulars of the character’s means of locomotion. Combinations of steering behaviors can be used to achieve higher level goals This paper divides motion behavior into three levels. It will focus on the (For example: get from here to there while avoiding obstacles, follow this corridor, join that group of characters...) middle level of steering behaviors, briefly describe the lower level of locomotion, and touch lightly on the higher level of goal setting and strategy. Introduction Autonomous characters are a type of autonomous agent intended for use in computer animation and interactive media such as games and virtual reality.

...Theory: The free fall is a known example or the most common example of a uniformly accelerated movement, with an acceleration a = -9.8m/s2 (vertical axis pointing vertically upward). If you choose the vertical axis pointing vertically downward, the acceleration is taken as + 9.8m/s2. The kinematic equations for a rectilinear movement under the acceleration of gravity are the same as any movement with constant acceleration: (1) v = vi - gt velocity as function of time. (2) y - yi = ½(vi + v)t displacement as function of time (3) y - yi = vit - ½gt2 displacement as function of time (4) v2 = vi2 -2g(x - xi) velocity as function of displacement The sub index i denotes initial quantities, g the gravity acceleration and t, the time. But for this type of motion, the displacement of the object as a function of time is described mathematically as: (5) ∆y=Vot + ½gt2 where Vo is the initial velocity of the object. If object if just drop velocity, Equation (5) becomes (6) ) ∆y=½gt2 Methodology Procedure: * A digital balance was used to measure the masses of the small and big steel balls. * A set-up of the free fall sensor was followed on the book. * The color-coded cables was connected to its color-coded socket. * Coach 6 free fall activity was clicked in the desktop of the computer. * The small steel ball was attached to the free fall sensor. * The steel ball was released...
