7. In the arrangement of the figure, billiard ball 1 moving at a speed of 1.95 m/s undergoes a glancing collision with identical billiard ball 2 that is at rest. After the collision, ball 2 moves at speed 1.01 m/s, at an angle of 02 = 58.7°. What are (a) the magnitude and (b) the direction (angle 01) of the velocity of ball
