Billiard ball A of mass mA = 0.116 kg moving with speed vA =2.80 m/s strikes ball B, initially at rest, of mass mB = 0.135 kg .As a result of the collision, ball A is deflected off at an angleof θ′A = 30.0∘ with a speed v′A = 2.10 m/s, and ball B moves with aspeed v′B at an angle of θ′B to original direction of motion ofball A. Solve these equations for the speed, v′B, of ball B afterthe collision. Do not assume the collision is elastic.
