I need A intial or Part 2 out of 2 (B) a inital the units are m/s^2

Dynamics

A parachutist is in free fall at a rate of 250 km/h when he opens his parachute at an altitude of 570 m. Following a rapid and constant deceleration, he then descends at a constant rate of 60 km/h from 556 m to 26 m, where he maneuvers the parachute into the wind to further slow his descent. Knowing that the parachutist lands with a negligible downward velocity, determine (a) the time required for the parachutist to land after opening his parachute, (b) the initial deceleration. t total = a initial =

Explanation / Answer

total time =35.246 sec

initial deceleration = 162.3 m/sec2
