0.300 kg baseball just before and just after it collides with a bat. just before, the ball has velocity of magnitude 12.0 m/s and angle u1 35.0°. just after, it is traveling directly upward with velocity of magnitude 10.0 m/s. the duration of the collision is 2.00 ms. what are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the impulse on the ball from the bat? what are the (c) magnitude and (d) direction of the average force on the ball from the bat?
