In a Little League baseball game, the 145 g ball enters the strike zone with a speed of 15.0 m/s . The batter hits the ball, and it leaves his bat with a speed of 25.0 m/s in exactly the opposite direction.

If the bat is in contact with the ball for 1.5 ms , what is the magnitude of the average force exerted by the bat on the ball?

A small, 150 g cart is moving at 1.90 m/s on a frictionless track when it collides with a larger, 5.00 kg cart at rest. After the collision, the small cart recoils at 0.810 m/s .

What is the speed of the large cart after the collision?
