(adsbygoogle = window.adsbygoogle || []).push({}); A 5.00 kg Ball A moving at 12.0 m/s collides with a stationary 4.00 kg Ball B. After

the collision, Ball A moves off at an angle of 38.0º right of its original direction. Ball B 52.0º left of Ball A's original direction. After the collision, what is the momentum

of Ball A?

P1 + P2 = P1' + P2'

60 + 0 = P1' + P2'

After this I have no idea where to go. We would need a velocity however there isnt one given.

I'm assuming a vector diagram would be useful, but Im not too sure what that would look like.
