A car accelerates from rest to a velocity of 5 meters/second in 4 seconds. What is its average acceleration over this period of time?
Its acceleration is 1.25 meters/second.
Its acceleration is 5 meters/second.
Its acceleration is 0.8 meters/second.
Its acceleration is 1.25 meters/second2.
Its acceleration is 20 meters.

5 m/s in 4 seconds
m/s/s = m/s^2

5/4 = 1.25

1.25 m/s/s = Its acceleration is 1.25 meters/second2.
