A bat hits a moving baseball. If the bat delivers a net eastward impulse of 1.3 N-s and the ball starts with an initial horizont al velocity of 3.8 m/s to the west and leaves with a 5.4 m/s velocity to the east, what is the mass of the ball (in grams)?
1 answer:
Answer:
Explanation:

Mass is impulse divided by change in velocity:
Hence, the mass of the ball is 141.30grams
