A 230 gram ball is moving horizontally to the right at 140 m / s when it is hit

Question

A 230 gram ball is moving horizontally to the right at 140m/s when it is hit toward the left by a metal club. The graph in the figure below shows the strength of the force this club exerts on the ball as a function of time (Figure 1) .

a) Find the magnitude of the ball's velocity just after it is hit by the club.

A 230 gram ball is moving horizontally to the right at 140m/s when it is hit toward the left by a metal club. The graph in the figure below shows the strength of the force this club exerts on the ball as a function of time (Figure 1). Find the magnitude of the ball's velocity just after it is hit by the club.

Explanation / Answer

Fav = 25.5/2

impulse = Fav x time = 25.5 x 5 /2 = 63.75

impulse = momentum (vf - vi)

63.75 = 0.230 (vf - (-140))

vf = 137.17 m/s to left
