A car traveling in a straight line has a velocity of 5.43 m/s at some instant. After 6.2 s, its velocity is 13.8 m/s. What is its average acceleration in this time interval? Answer in units of m/s

Explanation:

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

a = Δv / Δt

a = (13.8 m/s − 5.43 m/s) / 6.2 s

a = 1.35 m/s²
