On a separate occasion, Michael threatened to jump from the roof of hisoffice building as a demonstration of seasonal depression. If it takes 1.2seconds for his body to plummet to the ground,a. How fast will he be going when he reaches the ground?b. How far will he have fallen in meters?c. In feet?d. If Michael weighs 185 lbs, what would his force of collision with theground be, in Newtons, if his sudden deceleration upon impact takes0.1 seconds? ( 1 lb = 4.45 N, which means on Earth, a weight of 2.2lbs corresponds to a mass of 1 kg)
