The surfer in the photograph is catching a wave. Suppose you moved on the crest of a wave with a velocity of 1.73 m start / s, and the wave itself down until your speed reaches 11.4 m / s. The decrease in height is 2.52 m. If its mass is 70.9 kilograms, the quantity of work is not of (conservative) force of the waves made?

v1 = 1.73 m / s
V2 = 11.4 m / s
Work done = ΔKE - ΔPE ½ m = [(V2) ² - (v1) ²] - MGH
= 4501 - 1751 = 2750 joules
