Askydiver weighing 588 n reaches a velocity of 45 m/s [down] before opening her parachute. after falling an additional 30 m in 4 seconds, her velocity has decreased to 25 m/s.
what is the acceleration of the skydiver over the 30 m displacement?
what was the upward force exerted on the parachute during that time?
