A tennis ball is released from rest at the top of a tall building. Which graph best represents the variation with time t of the acceleration a of the ball as it falls, assuming that the effect of air resistance is not negligible?
Agraph showing acceleration starting at a positive maximum at t=0 and decreasing, tending towards zero over time.
Bgraph showing acceleration starting at a positive maximum at t=0 and decreasing, tending towards a constant non-zero positive value over time.
Cgraph showing acceleration starting at zero at t=0 and increasing, tending towards a constant non-zero positive value over time.
Dgraph showing a constant positive acceleration from t=0.
