I am stuck on this problem: A ball with a mass of M is on a frictionless curved track with a radius of R. The track sits atop a table that has height of H. Solve the following in terms of R,g,H, and M. a) the velocity of the ball b) the time it takes to hit the floor c) the distance D the ball lands from the base of the table d)the total amount of energy the ball has when it strikes the floor Here are my answers, are these correct. a) v= sqrt(2gH) ??? b) t=sqrt(2gh)/g ??? c)??? d) would i add 1/2mv^2 + MgR+MgH ???
