Question: A ball is shot from a compressed-air gun at twice its terminalspeed. (For the following, assume the drag force depends onv2)

1. What is the magnitude of the ball's initial acceleration, as amultiple of {\rm g} , if it is shotstraight up? Express your answer using one significantfigure.

2. What is the magnitude of the ball's initial acceleration, as amultiple of {\rm g} , if it is shotstraight down? Express your answer using one significantfigure.
