A parachutist whose mass is 75 kg drops from a helicopter hovering 1000 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance isproportional to the velocity of the parachutist, with the proportionality constant b, 30 N-secim when the chute is closed and by 100 N-secim when the chule is open if the chute does not openuntil the velocity of the parachutist reaches 20 m/sec, after how many seconds will the parachutist reach the ground? Assume that the acceleration due to gravity is 9.81 m/secThe parachutist will reach the ground after(Round to two decimal places as needed.)seconds.CHE

When a body is falling, it is acted upon by two forces which are gravitational force and air drag.…
