A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 68.6 m/s in
7.00 seconds. She then pulls the parachute cord and after a 4.00-second constant deceleration, descends at
9.0 m/s for 60.0 seconds, reaching the ground. From what height did the parachutist jump?

A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity
of 58.8 m/s in 6.00 seconds. She then pulls the parachute cord and after a 4.00-second
