歡迎來到Yogi老師解題給你看，今天我要講解的是AP Physics C Mechanics的問題
In the figure below, a block is released from rest at height d=37 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..
(a) Specify where the block first stops.
(b) Give the stopping point of the block, either as a distance along the first or second plateau (this would be a final stop) or as a height on the ramp at the right (this would be a momentary stop because the block will slide back down the ramp).
