Billiard ball A of mass 0.12kg moving with speed of 2.8m/s strikes ball B, initially at rest, of mass 0.14kg. As a result of the collision, ball A is deflected off at an angle of 30.0° with a speed of 2.1m/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 (velocity of ball www B after collision) and angle (angle of ball b after collision). Do not assume the collision is elastic.
