A pool ball moves at 2.0 m/s to the right (+x direction) and hits an identical, stationary ball. After the first ball strikes the 2nd ball, the first ball's velocity is 1.841 m/s, at an angle of +23. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball’s (a) speed and (b) direction after the collision.
