Final answer:
The acceleration of an NFL caliber wide receiver who reaches a top speed of 12.0 m/s in 2.4 seconds is 5.0 m/s², starting from rest.
Step-by-step explanation:
If an NFL caliber wide receiver starts from rest and reaches a top speed of 12.0 m/s in only 2.4 seconds, we can calculate their acceleration using the formula a = ∆v/∆t, where ∆v is the change in velocity and ∆t is the change in time. Since the wide receiver starts from rest, the change in velocity is 12.0 m/s, and the time taken is 2.4 seconds. Applying these values,
Acceleration a = ∆v/∆t = 12.0 m/s / 2.4 s = 5.0 m/s².
Therefore, the correct answer is (c) 5.0 m/s².
