Question

Billiard ball A of mass mA = 0.130 kg moving with speed vA = 2.65 m/s strikes ball B, initially at rest, of mass mB = 0.140 kg . As a result of the collision, ball A is deflected off at an angle of 30.5 ∘ with a speed vA1 = 2.35 m/s .

A.) Taking the x axis to be the original direction of motion of ball A, write down the equation expressing the conservation of momentum for the components in the x direction. Assume the velocity of ball B after collision is vB1.

B.) Write down the equation expressing the conservation of momentum for the components in the y direction.

Express your answersw symbolically in terms of the variables mA, mB, vA, vA1, vB1, θA, and θB.
