B. Set Hill 1 to T5 cm and the other hills to 0 cm. What is the height in meters? C. What is the potential energy of the car, in joules? ?. Calculate: Kinetic energy (K) depends on the mass and speed (v) of the object. The equation for kinetic energy is: szw With Hill 1 set to T5 cm, click Play and allow the car to reach the bottom. A. What is the final speed of the car. in meters per second? B. What is the kinetic energy of the car, in joules? {Use the mass in kg.) C. How does the car's kinetic energy at the bottom of the hill compare to its potential energy at the top? 8. Challenge: With no lriction, you can use the relationship between potential and kinetic energy to predict the speed of the car at the bottom of this hill from its starting height. To do this. start by setting the kinetic and potential energy equations equal to one another: K:U va=mgh A. Use algebra to solve for the speed. v =
