A skydiver falls a distance d 512 m in a time t 8.2 s before opening her parachute. After 90.2 s. Use a coordinate the chute opens, she falls an additional distance d = 1084 m in t system where the +y axis points upward. = A. What is the skydiver's average speed during the period before opening the chute, v? B. What is the skydiver's average speed during the period after opening the chute, v? C. What is the skydiver's average velocity over the entire fall, Vave? D. All the acceleration of the skydiver (while the chute was opening) occurred in a short time At = 2.0 s. What is the skydiver's average acceleration during that time interval?
