2. (2D Momentum) Ball 1 with mass m = 1kg and speed w = 5 m/s elastically collides with a stationary, identical ball 2 (resting on a frictionless surface). Ball 2 emerges from the collision at an angle 0, = 37, as shown in the figure. !3! a. Find the speed vs. (10 points) Before After collision collision b. Find the speed t. (5 points) c. What does 0, + 0: add up to? (5 points) Va (This is a characteristic of all elastic collisions between identical masses in Ball 2 Ball 1 Vif 2D.) 2.
