Problem: Two water­slide riders, A and B, start from rest at the same time and same height h but on differently shaped slides. Which rider is traveling faster at the bottom? Which rider makes it to the bottom first? Ignore friction and assume both slides have the same path length.

FREE Expert Solution

The height from which the slides start is the same despite having different shapes. 

The two slides also have the same path length.

From the conservation of mechanical energy:

(1/2)mv2 = mgh
