Problem

A block of mass

m

is released from rest from a vertical height

H

and slides down a smooth surface. Whether the surface is a straight inclined plane or an arbitrarily curved downward track, the final speed

v

of the block upon reaching the bottom horizontal level is purely a function of height and gravity, given by

v =
