2. A parachutist with mass 100 kg drops from an altitude of 3000 m. Assume that the airresistance is proportional to the velocity. During freefall, a downward velocity of 5 m/scauses a resistive force of 100 N. The resistive force of an open parachute is 5 times that offreefall. Determine the time when the parachuter reaches the ground if the time of freefall is(a) 30 seconds,(b) 1 minute.Hint: You will solve a transcendental equation. Try a numerical technique (e.g. Newton'smethod) or computational software.
