A parachutist after bailing out falls `80 m` without friction. When the parachute opens, he decelerates downward with `5m//s^(2)` and reaches the ground with a speed of `10 m//s`. (a) How long is the parachutist in air? (b) At what height did bail out?

A parachutist after bailing out falls 52 m without friction. When the parachute opens, she decelerates at 2.1 ms^(-2) & reaches the ground with a speed of 2.9 ms^(-1) . (i) How long has been the parachutist in the air? (ii) At what height did the fall begin?
