A cue ball initiallymoving at 4.3m/s strikes

a stationary eight ball of the same size and

mass. After the collision, the cue ballâs final

speed is 2 m/s .Find the cue ballâs angle with respect to

its original line of motion. Consider this to

be an elastic collision (ignoring friction and

rotational motion).

Answer in units of degrees.
