A small ball of mass mi = 0.240 kg is moving at a speed of 2.80 m/s. It strikes a stationary larger ball of mass m2 = 0.580 kg. After the collision, the balls follow the path shown in the figure, where a = 23.0 and = 51.0. What is the magnitude of the velocity of the larger ball after the collision? (Neglect friction and rotational motion.)
