1. The problem statement, all variables and given/known data A block of mass m=1.3 kg slides down a frictionless track, as in the attachment diagram. The block is released at height h=4m. The radius of the curvature of the track at the bottom is R=1m. What is the force of the track on the block at A? 2. Relevant equations Fg+N=0 3. The attempt at a solution I assumed that the track would be applying the normal force on the block, but the block does have some velocity and acceleration once it hits the bottom of the track, but I am not sure how to incorporate those.
