Question

Danny wants to construct a device that demonstrates one of Newton's laws of motion. He makes a small cart and adds marbles to it. He then places it on a ramp with a small wall at the end of the ramp. When he releases the cart, it accelerates down the ramp until it hits the small wall at the end. His setup is shown below.
