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?
