Group Work 3 – GI Joe (option 2)
G. I. Joe paratrooper Ripcord (80 kg) is invading Cobra HQ. He’sbrought in by a stealth bomber, where he jumps from an altitude of10,000 ft (approx 3000 meters).
What is his initial acceleration?
If the chute failed, what would his average acceleration be overthe trip? Assuming the average acceleration, how fast would he hitthe ground?
Derive an equation for the ratio of terminal velocities betweendiving head first vs. spread eagle (lying flat).
At 1,000 ft, he pulls the parachute cord (a 1m x 5m rectangularchute). What is his initial acceleration due to drag?
How long does it take to reach the ground at Cobra HQ if theparachute opens at 1,000 ft?
