Q. Billiard ball A of mass mA=0.400kg moving with speed vA=1.80m/s strikes ball B, initially at rest of mass mB=0.500kg. As a result of the collision, ball A is deflected off at an angle of 30.0 degrees with a speed of vA=1.10m/s. (a) Taking the x axis to be the original direction of motion of ball A, write down the equations expressing the conservation of momentum for the components in the x and y directions separately. (b) solve these equations for the speed vB and angle thetaB of ball B. Do not assume the collision is elastic.
