Transcribed Image Text:A parachutist whose mass is 60 kg drops from a helicopter hovering 1000 meters above the ground and falls toward the earth. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportionality constant b1 = 20 N/sec when the chute is closed and b2 = 90 N-sec/m when the chute is open. If the parachute does not open until after 10 seconds, how far will the parachutist reach in that time? Assume that the acceleration due to gravity is 9.8 m/sec².
