An average person can reach a maximum height of about 60 cm when jumping straight up from a crouched position. During the jump itself, the person’s body from the knees up typically rises at a distance of around 60 cm. To keep the calculations simple and yet get a reasonable result, assume that the entire body rises this much during the jump. (a) With what initial speed does the person leave the ground to reach a height of 60 cm? (b) Draw a free-body diagram of the person during the jump. (c) In terms of this jumper’s weight w, what force does the ground exert on him or her during the jump?
An eagle is flying horizontally at 7.7 m/s with a fish in its claws. It accidentally drops the fish. (in seconds)
(a) How much time passes before the fish's speed quadruples?(b) How much additional time would be required for the fish's speed to quadruple again?
6.00k, with t in seconds and r in meters.
