60\" (9 C . D C?) ' 0.088 m r E ' (MSG m . Two spheres A and B (of mass m each) were red vertically from the ground with different initial velocities at different times. When sphere A reached its summit, sphere B, with an upward velocity of [ 1] mls _ _ _, created a head-on collision with A. The impact caused sphere A to break into two pieces, each of mass m/Z. Knowing one-piece reached Point C and the other piece reached point B after the collision, determine: (a) the velocity of sphere B after the collision; (b) the angle 6 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
