Figure \(\mathrm{P} 10. 16\) represents two stroboscopic pictures (taken at the same flash rate) of a block moving along a ramp that exerts a frictional force on the block. In one sketch, the block is released from rest at the top of the ramp and moves downward. In the other sketch, the block is placed at the bottom of the ramp and shoved up the ramp. Which sketch is for the downward motion? Which is for the upward motion?
