Answer:
Final speed of the ball = 15.9375 m/s
Explanation:
We can apply momentum conservation in the direction of motion of the two balls.
According to law of conservation of momentum, the sum of momentum of the two balls before and after the impact remains conserved.
Momentum = mass [tex]\times[/tex] speed
Initial momentum = 0.17 [tex]\times[/tex] 15
= 2.55 kg m/s
But after the collision, the cue ball comes to rest. So there's only momentum for the second ball.
Final momentum = 0.16[tex]\times[/tex] v = 2.55
v = 15.9375 m/s
This is the final speed of the second ball.
