Problem
Two smooth slides start at the same elevation and end at the same lower elevation. Slide A is very steep at first and then levels out, while Slide B has a gentle, nearly constant slope. A small block is released from rest at the top of each slide. Which statement best describes the block’s speed as it reaches the bottom of each slide?
(a) The block on Slide A is faster than the block on Slide B.
(b) The block on Slide B is faster than the block on Slide A.
(c) Both blocks have the same speed.
(d) The relative speeds cannot be determined without knowing the blocks’ masses.
