yanni is sitting in the stands watching a football game. the quarterback runs forward toward the end zone and throws a pass straight downfield to a player for a touchdown. the quarterback ran at a speed of 8 m/s and threw the ball with a speed of 15 m/s. which statement is supported by this scenario? for yanni, the speed of the ball is 23 m/s, and for the quarterback, the speed of the ball is 15 m/s. for yanni, the speed of the ball is 15 m/s, and for the quarterback, the speed of the ball is 8 m/s. for both yanni and the quarterback, the speed of the ball is 23 m/s. for both yanni and the quarterback, the speed of the ball is 15 m/s.

Answer

Answer:

A. 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:

Step1: Analyze relative - motion concept

The quarterback is running at 8 m/s and throws the ball at 15 m/s forward.

Step2: Calculate Yanni's perspective

From Yanni's stationary position, the speed of the ball is the sum of the quarterback's running speed and the ball - throwing speed. So, $8 + 15=23$ m/s.

Step3: Determine quarterback's perspective

The quarterback is moving with the ball initially. So, the speed of the ball relative to the quarterback is just the speed at which he throws the ball, which is 15 m/s.
