Answer 2

The statement supported by this scenario is, for Yanni, the speed of the ball is 23 m/s, and for the quarterback, the speed of the ball is 15 m/s.

Relative speed of the ball

The relative speed of the ball is determined with respect to frame of reference.

For Yanni at rest ( zero speed);

Vr/b = va + vb

Vr/b = 8 + 15 = 23 m/s

For quarterback in motion

Vr/b = va + vb

Vr/b = 0 + 15 = 15 m/s

Thus, the statement supported by this scenario is, for Yanni, the speed of the ball is 23 m/s, and for the quarterback, the speed of the ball is 15 m/s.
