Pediatric calculations Accurate doses are especially important in giving medications to infants and children because even small errors can be dangerous due to their small body size. Two methods are used to calculate pediatric dosages: According to the weight in kilograms (kg) According to the child's body surface area (BSA) Calculations based on body weight 1. The first step is to convert the child's body weight into kg. The formula is 2.2 lb. = 1 kg. 2. The second step is to calculate

graph for the spring is also shown. [pic] [pic] Question 2 What is the spring constant for the spring inside the cannon? Question 3 How much energy is stored in the spring when it is fully compressed by 8.0 m'? Question 4 Cleo has a mass of 50 kg. Calculate Cleo's velocity just as she leaves the mouth of the cannon, assuming that the spring has transferred all of its energy to Cleo at this point. Question 5 The length of the cannon is 8.0 m. What is the net average force exerted

Physics is a large subject that can be observed almost everywhere, even in a theme park, in a theme park physics principles such as ‘weightlessness’ and ‘acceleration/deceleration’ play a large part in ensuring that the rides are as thrilling as they are safe. In this essay I am going to show how two certain physics principles are being used in a ride to ensure that the ride is safe but at the same time delivers a lot of thrill to the rider. I am going to explore the sense of ‘weightlessness’

Answer the following questions while in the Phase 5 lab environment. Section 1 – From the left of the screen to the right, the red balls have a center of mass placed at 20 feet, 15 feet, and 10 feet high respectively. 1. Suppose each red ball weighs 20 lbs. Find the potential energy (PE) for each ball on each ramp. In this lab mass is given in pounds and height is in feet, so use 32.2 ft/sec2 as the gravitational constant. Your answer will be in foot-pounds since US units are being used

ropewalker’s chances of success. Picture the rope as the axis. When a tightrope walker embarks on his journey, he must stay constantly positioned over that axis to maintain balance. Carrying a pole horizontally helps to distribute the ropewalker’s mass laterally in a direction away from the axis, or rope. Having a pole in hand helps to increase stability because the ends of the pole are constantly being acted upon by a variety of forces that are trying to change their position in the air with every

Rollercoasters are driven by different forces of gravity, inertia and centripetal. The physics used in a rollercoaster also involves friction, work, air resistance, and energy. It usually begins with a mechanical device i.e. motor and chain; they exert a force on the roller coaster car train to lift them to the top of the hill. From this point, gravity starts operating, and the duration of the ride undergo energy transformation. Pulling the rollercoasters uphill uses energy, this energy does not
