While messing around with billiard balls, you roll the 8-ball into another ball of the same mass and initially at rest. After the collision, the 8-ball ball moves at 3.50 m/s along a line making an angle of 24.0° with its original direction of motion, and the second ball has a speed of 1.90 m/s. Assume that the frictional force of the table on the billiard balls is negligible during the interaction.

(a) Find the angle between the direction of motion of the second ball and the original direction of motion of the 8-ball ball.

(b) Find the original speed of the cue ball.
