Imagine a skydiver who waits a long time before opening her parachute. For simplicity, assume she moves along a straight line. (a) In what direction is the skydiver moving (what is the direction of her velocity) just before she opens her parachute? (b) Suppose that when she finally opens her parachute, she is traveling faster than her terminal speed with the parachute open. What is the direction of the skydiver’s acceleration just after she opens her parachute?
