POOL TABLE PROBLEM. When ball 1 hits ball 2, they both go off at different angles. What is the final velocity of the second ball? GIVEN: ball 1=4 kg ball 2= 10 kg Vo1=8 m/s Vf1=3 m/s Vo2=0 θ=34 ° (ball 2 moves at a speed of 3 m/s @ 34°) Solve for Vf2 and the angle for ball 2 after the collision (Angle β) Relevant equations: m1vo1 + m2vo2 = m1vf1 + m2vf2 i did (4)(8) + 0 = (10)(vf2) i had no clue if this was right though. are you supposed to use sin, cos, or tan θ?
