A parachutist leaves a stationary plane and free falls for 50.0 meters (ignore air resistance for the free fall). The parachute then opens and the aparachutist begins to slow down at the rate of 2.00 m/s^2. She reaches the ground with a speed of 3.00 m/s.
a.) How long is the parachutist in the air?
b.) At what height did she leave the plane?
c.) Sketch a position vs. time graph, a Velocity vs. time graph and an acceleration vs. time graph for the motion.
