For Yanni, the speed of the ball is 23 m/s, and for the quarterback, the speed of the ball is 15 m/s.

Explanation: The 15 m/s is the speed of the ball relative to the moving quarterback. An observer on the ground (Yanni) sees the ball's speed as the quarterback's speed plus the thrown speed in the same direction: 8 m/s + 15 m/s = 23 m/s.
