A billiard ball A moving at a speed of 2.4 m / s bumps into a
billiard ball B of the same mass, which
are at rest. After the impact, A moves at a speed of 1.4 m / s in a
direction that forms the angle 50 ◦
with A's original direction of movement. Determine the magnitude
and direction of B's velocity vector by
the impact. (Answer 1.8 m / s; 36 ◦)
