Suppose the force acting on a tennis ball (mass 0.060 kg) points in the + x direction and is given by the graph of Fig. 7-33 as a function of time. Use graphical methods to estimate
(a) The total impulse given the ball, and
(b) The velocity of the ball after being struck, assuming the ball is being served so it is nearly at rest initially.
