Physics 21110/30 HW HandoutDue Friday 11/1Fall 20022-D Momentum and Energy1)A 2kg ball (1) collides with a stationary ball (2) of the same mass. Ball 1 moves off at the angle θ1with velocity v1,fafter the collision. All angles are measured with respect to the incoming velocity vector of ball 1. In all the followingcases, draw a vector that represents themomentum of ball 2 after the collisionas in the example at right. Then, using p1,iand the x and y components of p1,fdetermine p2,fand v2,f. Find both magnitude and direction in each case. Note: The momentum vectors arein the same proportion as the velocity vectors onlywhen the masses are the same!Now take the results of the previous HW and determine which of the following are elastic and which
