Science

PART A

Look at t diagram below. Karl swings a 600-g bat toward the ball. Chris swings a 750-g bat toward the ball.

mass of bat: mass of bat:
600 g 750g
velocity of wings: velocity of swing:
20 m/sec 12 m/sec

Karl Chris

Use the data to compare the momentum of the two bats.

PART B

The same-size ball is pitched to Karl and Chris at the same speed. How can their bats change the direction, velocity,and acceleration of the ball? Which bat will have a greater effect on the ball? Use the concept of momentum in your answer.
