Question

After leaving a platform, the velocity with which a diver enters the water is directly proportional to the
square root of the height of the platform. When a diver jumps off a 10-meter platform, they will strike
the water at 46 feet per second. In Acapulco, Mexico cliff divers plunge 135 feet into the water below.

Answer 1

I assume you want the velocity from that height.

v = k√h
so, v/√h = k, a constant.
so, you want v such that
v/√135 = 46/√(10*3.28)
