Physics: energy conservation?
A small block with mass 0.0450 slides in a vertical circle of radius 0.0730 on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block's path, the normal force the track exerts on the block has magnitude 3.55
What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path?
What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path?
it seems like the work is right but i get the wrong answer for some reason...
