Homework Statement
A 2.0 kg ball moving with a speed of 3.0 m/s hits, elastically, an identical stationary ball. If the first ball moves away with an angle 30 degrees to the original path, determine the speed of the first ball after the collision, and the speed and direction of the second ball after the collision.
Homework Equations
v_1 = V_1cos30 + v_2cos(theta) for the movement in the "x" direction
and
0 = v_1cos30 + v_2cos(theta) for movement in the "y" directions
The Attempt at a Solution
Played with this for hours but to me it does not seem like there is enough information. I feel like I am missing at velocity for after the collision.
Thanks
