1. A baseball with a mass if 145 g and a velocity of 58.0i m/s is hit by the batter and goes straight up with a new velocity of 39.0j m/s. Determine the magnitude of the change in momentum of the baseball. (change in momentum is a vector with x and y components. Find the magnitude of this vector.

2. If the baseball in the previous problem is in contact with the bat for 1.16 milliseconds, determine the magnitude of the average force the ball exerts on the bat.
