(II) Billiard ball A of mass ma = 0.120 kg moving with speed vA = 2.80 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 30.0° with a speed vA = 2.10 m/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 compo- nents in the x and y directions separately. (b) Solve these equations for the speed, vg, and angle, 0g , of ball B after the collision. Do not assume the collision is elastic.
