1. The problem statement, all variables and given/known data 1. A crate with scientific equipment slides down a curved frictionless side of lunar crater of the depth h, and then up along the other side which is an inclined plane as in Figure 2. The coefficient of kinetic friction between crate and incline is k, and the inclined side makes an angle θ with the horizontal. Use energy methods to find the maximum height ymax reached by the crate. 2. Relevant equations 3. The attempt at a solution The equation I have come up with so far is mgy=mgh-(Mu sub k *n)y/sin(theta) I know this is correct, but how would one calculate what the normal force would be? or is it sufficient to simply solve for y?
