What is the acceleration of a car that has a velocity of 20 m/s, and

increase to a velocity of 70 m/s in 5 seconds?

Acceleration of Car = 10 ms⁻²

Explanation:

Step 1:

The basic formula of acceleration is a = (v-u) / t ms⁻²

where, v - final velocity

u - initial velocity

t = time taken

Step 2:

Here v = 70 ms⁻¹

u = 50 ms⁻¹

t = 5 s

∴ a = (70 - 20) / 5

a = 10 ms⁻²
