Momentum

A pitcher throws a slow ball straight across the plate at 40.0 m/s. The batter hits the 0.200 kg ball straight back at 60.0 m/s. If the bat is in contact with the ball for 0.500s,

a) What is the initial momentum of the ball?

b) What is the final momentum of the ball?

c) What is the change in momentum of the ball?

d) Use the impulse-momentum theorem to find the force experienced by the ball.

Please explain the equations and show the work as I have no idea what I am doing. Please state what each letter in the equation stands for.

Momentum is represented by p and is the product of mass and velocity.

p = mv

Solution Summary

Momentum (and velocity) is a vector quantity so we have to define ourselves a positive direction (to batter) and a negative direction (to pitcher).
