A paratrooper is initially falling downward at a speed of 33.0 m/s before her parachute opens. When it opens, she experiences an upward instantaneous acceleration of 82 m/s2.
(a) If this acceleration remained constant, how much time would be required to reduce the paratrooper's speed to a safe 4.75 m/s? (Actually the acceleration is not constant in this case, but the equations of constant acceleration provide an easy estimate.)
(b) How far does the paratrooper fall during this time interval?
