Gerri leaves the long jump takeoff board with a vertical velocity of 2.8m/s upward and a horizontal velocity of 7.7m/s. Gerri is in the air for 0.71 seconds before she hits the ground. Gerri’s center of gravity was 1m high (relative to the ground) at the instant of takeoff. Assume that the effect of air resistance is negligible and that the upward direction is positive. How high is Gerri's center of gravity at the end of her flight, when she first hits the pit? Answer = .52m I NEED TO SEE THE WORK!!
