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.
Provide your answer for (a) and (b) with three significant digits of precision, and provide the direction in (b) in unit circle notation.
