    A high jumper (mass=70 kg) is competing in an Olympic event. The height she was trying to clear was when her CoG was 2.05 m above the ground (CoG was 1 m above ground at takeoff). While making the jump, the jumper’s foot was in contact with the ground for 0.22s during the upward phase of the jump. a. How much change in potential energy must the jumper have to just clear the bar? (1 pt) b. What is the...

    Consider a bungee jumper dropping vertically in freefall from a bridge 80 m above the ground. After three seconds, the elastic cord connecting the jumper to the bridge starts to stretch, which changes the jumper's acceleration to 15 m/s2 upwards. a) Sketch (without doing any math) the position vs time, velocity vs. time, and acceleration vs. time graphs for the bungee jumper from the moment they start to fall to the moment they reach the closest to the ground. b)...

    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...
