A ball falls straight down through the air under the influence of gravity. There is a retarding force F on the ball with magnitude given by F = av^2, where "v" is the speed of the ball and "a" is a positive constant. The ball reaches a terminal velocity after a time t. The magnitude of the acceleration and velocity at time t/2 is Increasing, Decreasing
