- Homework Statement
- A billiard ball moving at 5 m/s strikes a stationary ball of the same mass. after the collision, the original ball moves at a velocity of 4.35 m/s at an angle of 30° below its original motion. find the velocity and angle of the second ball after the collision.

- Relevant Equations
- Pi = Pf

P = mv

I'm guessing this question can be solved using the law of conservation of momentum

Vi = 5 m/s

(5 m/s) M = (4.33 m/s) cos30 M + V sinθ M

I don't know what to do after this... I'm also not sure if I use the sin and cos correctly.
