3. [Walker2 9.P.014.] A 0.14 kg baseball moves toward home plate with a velocity vi = (-25 m/s) x. After striking the bat, the ball moves vertically upward with a velocity vf = (13 m/s) y.
(a) Find the direction and magnitude of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 ms.
Don't I need to know what direction the baseball is moving in initially if I am to compute the direction of the impulse. Are they assuming that the ball travels completely horizontal? Or do I not understand this?
