Question

The tallest man to have ever lived was Robert Waldow. He was last measured in 1940 to be 2.72 meters tall (8 feet 11 inches). Determine the speed that a quarter would have reached bedor contact with the ground if dropped from rest from the top of his head.

Explanation / Answer

Use v2 = u2 + 2aH

here, Height H = 2.72m

a = acceleration due to gravity = g = 9.8 m/s2

and u = initial velocity = 0 m/s

therefore, v = [0 + 2(9.8)(2.72)]1/2 = 7.3015 m/s

this will be the speed of the quarter just before hitting the ground if dropped from Waldow's head.
