If the block is still moving, it then slides down a second frictionless ramp through height d/2 and onto a lower plateau, which has length d/2 and where the coef cient of kinetic friction is again k = 0. 5. If the block is still moving, it then slides up a frictionless ramp. If it is on a plateau, state which one and give the distance l from the left edge of that plateau. m d d d/2.
