To study effect of air resistance, a rubber ball was shot vertically upwards from a spring gun from 20th floor of a tall building. Velocity of the ball was recorded at regular intervals of time and the data obtained were plotted on a graph paper. Some of the marking on the axes are erased as shown in the following figure. With what speed did the ball strike the ground?
