How Do You Calculate Angular Momentum in a Ball and Bat Collision?

[gradyhawks]

Homework Statement

I need to find ω. The values I have are:

Ball of mass .16 KG is traveling horizontally at 54 ms^-1 and its struck by the bat. The ball still travels horizontally but in the opposite direct at speed 40ms^-1. The moment of inertia is 0.30kg about the pivot and hits the ball at a point that is 0.8m away from the pivot. After the collision the bat is still swinging in the same position but with a velocity of 0.35 ω

The Attempt at a Solution

Really unsure how to do this ... this test is due in an hours time and I am really struggling with this one. Any guidance would help no end!

(a bit late, but …)

in any collision, both ordinary momentum and angular momentum are conserved …

in this case, you would use conservation of angular momentum
