0.10- baseball moves toward home plate with a velocity = (-31 ).
After striking the bat, the ball moves vertically upward with a velocity = (21 ). Find the direction of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 . Find the magnitude of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 .
You have provided numbers without dimensions. One of the first things you must learn about physics is getting the dimensions right. When you have learned to do that, help can be provided.
For now, all I can tell you is that the impulse delivered, which is a vector, equals the VECTOR change in momentum of the ball.
