Two snooker balls, each of mass m, move freely on a frictionless, horizontal surface, as shown in Figure Q1(b). Ball A is moving at a speed v0 = 10 m/s when it hits ball B which is at rest and the impact causes ball B to break into two parts, each of mass m/2. One of the parts reaches Point C about 0.07 s after the collision and the other part reaches Point D about 0.09 s after the collision. Assume there is no y component in velocity ball A Explain with calculation how the velocity of ball A moves forward.
