Question

a car accelerates from rest to a velocity of 5meters/second in 4 seconds. what is its average acceleration over this period of time?​

Answer 1

Answer:

1.25 m/s²

Explanation:

Average acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (5 m/s − 0 m/s) / 4 s

a = 1.25 m/s²
