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 30.0o with a speed 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 θB of ball B. Do not assume the collision is elastic.
