Justify your answer. b. Which vehicle will experience the greater change in momentum? Justify your answer. c. Which vehicle will experience the greater acceleration? Justify your answer.A 0.13 kg baseball has a momentum of p = 11 kg*m/s as it is pitched toward home plate. A 4.2 kg bat swings at the baseball with a momentum of 28 kg*m/s and is in contact with the ball for 0.06 s. Assume the batter doesn't follow through like they should but instead the bat is at rest immediately after being in contact with the baseball (like bunting it). a.How much force was on the baseball when the bat was striking it? b.How much work was done on the baseball by the bat?A golf ball m = 0.155 kg strikes a vertical concrete wall elastically with a horizontal velocity of v = 15 m/s. a.
