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 2.7-second constant deceleration, descends at 10.5 m/s for 3.6 * 10 seconds, reaching the ground. From what height did the parachutist jump? answer in meters. (assume g = 9.8 m/s² )
