Question

A 145 g ball with an initial velocity of 55 m/s collides with a 1 kg baseball bat moving at 80 m/s in the opposite direction. The batter hits the ball at high speed directly back to the pitcher, and the pitcher makes a miraculous catch. Assume the batter stops the swing during the collision, transferring all of the momentum of the bat into the ball. This way, the last term is the ball only. The final term for the bat drops to 0. The x-axis is positive for the ball moving towards the pitcher and away from the batter. Use the conservation of momentum equation: Initial mass 1 * velocity 1 + Initial mass 2 * velocity 2 = Final mass 1 * velocity What is the final velocity of the baseball before the pitcher catches it? (Insert the number only without units.)
