Problem
A ball is projected vertically upward with an initial velocity of 15m s−1 and returns to the point of projection. Taking upward direction as positive and neglecting air resistance,
(i) sketch the velocity–time graph of the ball for its entire flight,
(ii) state from the graph the time at which the velocity becomes zero, and the total time of flight.
