A 146 gram baseball is hit toward the left by a bat. The magnitude of the force the bat exerts on the ball as a function of time is shown in the figure below (Figure 1) .Part AFind the magnitude of the impulse that the bat imparts to the ball.p = __________ kg*m/s}Part BFind the magnitude of the ball's velocity just after it is hit by the bat if the ball is initially at rest.v = _______________m/s}Part CFind the magnitude of the ball's velocity just after it is hit by the bat if the ball is initially moving to the right at 31.5m/ s} .v = _______________ m/s}
