Two spheres A and B (of mass m each) were fired vertically from the ground with different initial velocities at different times. When sphere A reached its summit, sphere B, with an upward velocity of 5.6 m/s created a head-on collision with A. The impact caused sphere A to break into two pieces, each of mass m/2. Knowing one-piece reached Point C and the other piece reached point D after the collision,determine: (a) the velocity of sphere B after the collision; (b) the angle and the speeds of the two pieces after the collision; and (c) the force exerted by sphere A on B if the collision occurred in 0.001 s.
