Q. A 54.00 kg bungee jumper has fallen far enough that her bungee cord is beginning to stretch and resist her downward motion. Find out the force (magnitude and direction) exerted on her by the bungee cord at an instant while her downward acceleration has a magnitude of 6.6 m/s2. Overlook the effects of air resistance. Take the upward direction as positive.
