Billiard ball A of mass mA = 0.120 kg moving with speed vA = 2.70 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 28.5 with a speed vA1 = 2.05 m/s . Part 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 . Express your answer symbolically in terms of the variables mA , mB , vA , vA1 , vB1 , A , and B .Part B

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