If the velocity of a moving car increases from 9.0 m/s to 25.0 m/s in the span of 5 seconds, what is the average acceleration during this time period, in m/s2

3.5m/s²

Explanation:

Acceleration is defined as the change in velocity per unit of time.

Acceleration (a) = ΔV / t

V₁ = 9.0m/s

V₂ = 25.0m/s

ΔV = V₂ - V₁

25 - 9

ΔV = 16m/s

a = 16/5

= 3.5m/s²

Acceleration during this period is 3.5m/s²

it is 3.5 miles per hour
