A cart of mass m = 1.4 kg is released from the top of a ramp sloped ? = 13° relative to the horizontal. The length of the ramp is L =9.6 m. For such a situation, the acceleration of the cart is a = gsin(?), where we use g = 9.8 m/s2, and the distance traveled along the slope at any given time can be shown to be at2/2 using calculus. Let us set the Gravitational Potential Energy to be 0 at the bottom of the ramp. Find the Gravitational Potential Energy, GPE, and the Kinetic Energy, KE, at the following times: (neglect friction and air resistance)

What is the car's Kinetic Energy at the bottom of the ramp?
