A 1 kg bat hits a 150 g baseball travelling at 40 m/s opposite to the bat’s direction. This collision lasts 1/1000 of a second. Immediately after it is hit the baseball has a velocity of 50 m/s opposite to its initial direction and the bat 10 m/s in the same direction as the as it moved initially. Draw a momentum chart for the collision and find the average force on the bat.

Sounds like homework so may get moved to that section.

Have you tried to solve it yourself?

Its study prep for a quiz I have. Im assuming the initial momentum for both will be a vector of the same length, just in an opposite direction for each one. And then final momentum for the baseball is a vector in the other direction just a little bit longer, and for the baseball its a same direction vector but alot shorter. Is this correct?

The initial velocity of the bat isn't given. I believe you will have to calculate it from the data before and after the impact.
