Centripetal Acceleration and Centripetal Force 1. What is the centripetal acceleration of a point on the perimeter of a bicycle wheel of diameter 70. cm when a bike is moving at 8.0 m/s? 2. A pilot is upside down at the top of an inverted loop of radius 3.20 x 103 m. At the top of the loop his normal force is only one-half his normal weight. How fast is he going? 3. The maximum force a pilot can stand is about seven times his weight. (This is his normal force.) What is the minimum radius of

velocity, the net force on it is zero. Why, then, do you continue running your engine? The engine continues to run because there is force working against the vehicle. The tires rolling along the pavement create friction, as well as wind resistance hitting your windshield, create a force that can only be counteracted by the engine creating an equal or greater opposing foce. 17.

of Motion The second law states that the net force on an object is equal to the rate of change (that is, the derivative) of its linear momentum pin an inertial reference frame: The second law can also be stated in terms of an object's acceleration. Since the law is valid only for constant-mass systems,[16][17][18] the mass can be taken outside the differentiation operator by the constant factor rule in differentiation. Thus, where F is the net force applied, m is the mass of the body, and a is

acceleration is positive and has the largest magnitude ( label this as A). 6. A body of mass m is placed on a horizontal plate that under goes vertical SHM The amplitude of SHM is A and the frequency is f. (a) Derive an expression for the reaction force on the particle from the plate when the particle is at its highest position. (b) Using the expression in

PHYSICS I 1. The steps for the scientific method are listed in chapter 1. List and explain each of the steps in the scientific method in the context of the following situation. You do not have to resolve the question; just explain the steps for resolving the question: It is well known that objects expand when heated. An iron plate will get slightly larger when put in a hot oven. Suppose an iron plate has a hole cut in the center. Will the hole get larger or smaller when the plate is heated

The circus has come to town and the principal attraction is Cleo, the human cannonball. There is a large compressed spring at the base of the cannon as illustrated below. It is this spring that will propel Cleo out of the cannon through the air to the safety net. The force-compression graph for the spring
