Calculate: Kinetic energy (K) depends on the mass and speed (v) of the object. The equation for kinetic energy is: K = mv2
With Hill 1 set to 75 cm, click Play and allow the car to reach the bottom.

What is the final speed of the car, in meters per second?

What is the kinetic energy of the car, in joules? (Use the mass in kg.)
0.386 J
How does the car’s kinetic energy at the bottom of the hill compare to its potential energy at the top?
