A runner starts from rest and accelerates uniformly to a speed of 8.0 meters per

second in 4.0 seconds. The magnitude of the acceleration of the runner is

0

32 m/s/s

O 9.8 m/s/s

o 2.0 m/s/s

0

0.50 m/s/s

2 m/s²

Step-by-step explanation:

Step 1:

Let the initial velocity be 0 m/s and the final velocity be 8 m/s and the time traveled is 4 s.

From the basic science,

Acceleration = (Final Velocity - Initial Velocity) / Time

Step 2:

Acceleration = (8-0) / 4

2 m/s²
