find magnitude and direction please

A billiard ball moving at 5.80 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.92 m/s at an angle of 32.0 with respect to the
original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision.
2 827
Check the initial and final kinetic energies. You will find that your final kinetic energy is not equl to the initial kinetic energy, m/s
-63 55
There are three equations relating the final velocities to the initial velocities (two from momentum conservation and one from energy conservation), but we
only have two unknowns (the final speed and direction of the second ball) You thus have some fiexbitity in choosing equations to work with, (with respect
to the original line of motion)
