Question

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?

Answer 1

Acceleration of Car = 10 ms⁻²

Step-by-step 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
