A long track balanced like a seesaw supports a gold ball and a more massive billiard ball with a compressed spring between the two as shown in the figure. The CG of the two ball system is therefore directly above the point of support (the triangular fulcrum). When the spring is released, the balls move away from each other. As the balls roll outward, will the track remain in balance, or will it tip? What principles do you use for your explanation?

HMMM - I think this needs you to ignore the 'rolling' of the balls

It can be answered if you assume the balls are ejected without rolling, but unless you know the size and density of the two balls (and coefficient of friction...)you cannot actually answer this
