Answer:
For Yanni, the speed of the ball is 15 m/s, and for the quarterback, the speed of the ball is 8 m/s.
Explanation:
Zero.
Acceleration is defined as the change in velocity over time.
Since in your case there is no change, there is no acceleration, so it is zero:
Or in formula: <span>a=<span><span>Δv</span>t</span></span>
Where a=acceleration, <span>Δv</span>=change in velocity and t=time
The unit of acceleration would be m/s² :)
