3.12. Throwing a beach ball A beach ball is thrown upward with initial speed vo Assume that the drag force from the air is Fd-mav. What is the speed of the ball, vs right before it hits the ground? (An mplicit equation is sufficient.) Does the ball spend more time or less time in the air than it would if it were thrown in vacuum?
