Find at what height does the fall begin

Reference no: EM13524446

A parachutist bails out and freely falls 50 m. Then the parachute opens, and thereafter she decelerates at 1.8 m/s2. She reaches the ground with a speed of 2.8 m/s.

(a) How long is the parachutist in the air?

(b) At what height does the fall begin?
