Suppose the force acting on a tennis ball (mass 0.065 kg) points in the +x direction and is given by the graph of Fig. 7-30 as a function of time.
Figure 7-30 in attached document.
(a) Use a graphical method to estimate the total impulse given the ball.
(b) Use a graphical method to estimate the velocity of the ball after being struck, assuming the ball is being served so it is nearly at rest initially.
