a block is released from rest at height d = 28 cm and slides down a frictionless ramp and onto a first plateau, which has length d and where the coefficient of kinetic friction is 0.50. If the block is still moving, it then slides down a second frictionless ramp through a height of d/2 and onto a lower plateau, which has length d/2 and where the coefficient of kinetic friction is again 0.50. If the block is still moving, it then slides up a frictionless ramp until it (momentarily) stops.

Give the stopping point of the block, either as a distance along the first or second plateau

Question

a block is released from rest at height d = 28 cm and slides down a frictionless ramp and onto a first plateau, which has length d and where the coefficient of kinetic friction is 0.50. If the block is still moving, it then slides down a second frictionless ramp through a height of d/2 and onto a lower plateau, which has length d/2 and where the coefficient of kinetic friction is again 0.50. If the block is still moving, it then slides up a frictionless ramp until it (momentarily) stops.

Give the stopping point of the block, either as a distance along the first or second plateau

(this would be a momentary stop because the block will slide back down the ramp)

You need to sketch this and label first, this is a multi-stage problem and you need to keep track for 4 velocities plus one quadratic or two halves for the last part.  People will be willing to help you understand if you get stuck, but you're going to have to do the work on this one yourself mmk?  ;-)
