The first recorded parachute jump in Canada was made at Vancouver on May 24, 1912 by Charles Saunder. If a parachutist waits until opening the parachute, he will free-fall for a short time before reaching terminal velocity. Upon opening the parachute he will quickly decelerate then descend at a constant velocity until reaching the ground. 16. Sketch the velocity-time graph of the different parts of his motion from the airplane to the ground. [Appendix A] A. Jumps from airplane. B. Reaches terminal velocity. C.
