Masses of the bodies \( A, B \) and \( C \) are \( 1 \mathrm{~kg}, 2 \mathrm{~kg} \) and \( 3 \mathrm{~kg} \) respectively. There is no friction between the ground and the bodies. Initially ball \( A \) is moving with a velocity \( 20 \mathrm{~m} / \mathrm{s} \) collides inelastically \( (e=0.5) \) with the ball \( B \), which was initially at rest. The ball \( B \) further collides elastically to the block \( C \) (at rest), and then \( C \) collides elastically to the wall in front. Find the velocities of the three blocks after all collisions occurred.
