A 1.0-kg cue ball traveling at 15 m/s strikes a stationary billiard ball of mass 1.5 kg. After the collision, the cue ball remains at rest. With what velocity does the other ball travel?

Respuesta :

mberisso

Answer:

Other ball's velocity is 10 m/s

Explanation:

We can use conservation of momentum:

[tex]P_{1i} +P_{2i} =P_{1i} +P_{2i}\\1 * 15 + 1.5 * 0 = 1 * 0 + 1.5 * v\\15 = 1.5 * v\\v=\frac{15}{1.5} \,\frac{m}{s} \\v=10 \,\frac{m}{s}[/tex]
