Determining the negligible downward velocity

Assignment Help Other Engineering
Reference no: EM13875651

A parachutist is in free fall at a rate of 180 ft/s when he opens his parachute at an altitude of 1900 ft. Following a rapid and constant deceleration, he then descends at a constant rate of 44 ft/s from 1800 ft to 100 ft, 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 initialdeceleration.
