A 0.150g baseball is thrown horizontally with a velocity of 28.0 m/s in the negative x-direction. It is hit by a bat, during a collision that lasts approximately 2.50ms, and has a new velocity of 30.0 m/s in the positive x-direction. Calculate the average force on the ball. (Give magnitude and indicate direction with a positive or negative sign.)
