An object weighing 45 N is dropped from the top of a high rise building and falls a distance of 31m to the ground. How much work does gravity do on the object from the time it is dropped to the time it hits the ground.

Formula for Work = W = fd
f= 45N W = 45(31) d= 31 m W = 1,395

A weightlifter presses a 325 N weight .35 m over his head in 4 seconds. What is the power of the weight lifter?

Power = p = w/t so you must first find work (w) for this problem
w= fd f= 325 N d = .35 W= ? fd or 325 (.35) w = 113.75 Now find Power p = w/t or work divided by time 113.75 / 4 = 45.5 Watts
