In a game of pool, the cue ball strikes another ball of the same mass and initially at rest. After the collision, the cue ball moves at 3.10 m/s along a line making an angle of 27.0° with its original direction of motion, and the second ball has a speed of 2.30 m/s. Find (a) the angle between the direction of motion of the second ball and the original direction of motion of the cue ball and (b) the original speed of the cue ball.

2. Relevant equations

Conservation of Momentum

3. The attempt at a solution

Not sure how to solve this at all. Only thing I am sure of is my drawing. What steps do I use to go about finding the angle?
