A sky diver jumps from a "perfectly good" plane Prior to opening their parachute they fell 750 m in 15.0s, and after opening their parachute they fell an additional 450 m in 250s. (a) What is their average velocity prior to opening the parachute? (b) What is their average velocity with the parachute opened? (c) What is the average velocity for the entire motion? (d) help draw a complete diagram of the situation.
