I haven't used the angle yet, I'm not sure how to use it to find the direction after the collision. I set up a momentum equation, and, since it's an elastic collision, I set up a KE equation with it. I had trouble when I ran through the equations: I solved for x in the MV equation, but I got a y...
the x is the velocity in the x direction, and same for y
I multiplied each mass times the velocity to get momentum. Then I set that P = MV1 + MV2 and I solved for the missing V. The angle is 140 degrees from 0. Counterclockwise.
Homework Statement
A 55kg man is running in the positive y direction at 4 m/s. He is tackled by a 115kg man running 8.5 m/s at a 140 degree angle. What is the speed and direction after the inelastic collision?

Homework Statement
A 2kg block is resting on a frictionless table. It is hit, head on, by a 1kg block heading at 4 m/s. The larger block is sitting 3m from the edge of a 5m long table. The collision happens with the smaller block's distance being 2m from the table and the larger blocks d =...
