A long track balanced like a seesaw supports a golf ball
Chapter 28, Problem 113TAD(choose chapter or problem)
A long track balanced like a seesaw supports a golf ball and a more massive billiard ball with a compressed spring between the two. When the spring is released, the balls move away from each other. Does the track tip clockwise, tip counterclockwise, or remain in balance as the balls roll outward? What principles do you use for your discussion and explanation?
