Q. A billiard ball of mass 0.400 kg moving with speed Va = 1.80 m/s strikes a second ball of mass 0.500 kg. As a result, the first ball is deflected off at an angle of 30.0 with a speed of Va' = 1.10 m/s. 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. Solve these equations for the speed, Vb', and angle of B'. Do not assume the collision is elastic.
