Acceleration due to Gravity

Acceleration due to Gravity problem 11

A parachutist jumps out of the plane and falls freely for two seconds. He then opens the parachute and his speed is reduced to 2 m/s in 4 s.

  • Calculate his speed before he opens the parachute.

  • What is his deceleration after opening the parachute?

  • From what minimum height must the parachutist jump in order for him to land at a speed of 2 m/s?
