Ulie gets into an airplane and waits on the tarmac for 2 min. before it takes off. the airplane climbs to 10,000 ft. over the next 15 min. after 2 min. at that constant elevation, julie jumps from the plane and free falls for 45 sec. until she reaches a height of 5,000 ft. deploying her chute, she slowly glides back to earth over the next 7 min. where she lands gently on the ground.
a. draw an elevation-versus-time graph to represent julie’s elevation with respect to time.
b. according to your graph, describe the manner in which the plane climbed to its elevation of 10,000 ft.
c. what assumption(s) did you make about falling after she opened the parachute?
