Question

A car starts to move from rest and covers a distance of 360m in one minute. Calculate the acceleration of the car.

Answer 1

The acceleration of car is 0.2 ms⁻²

Explanation:

When the car moves , the distance covered is calculated by the relation

S = u t + $\frac{1}{2}$ a t²

In this question u = 0 , because car was at rest initially

Thus S =  $\frac{1}{2}$ a t²

here S is displacement and a is the acceleration of car

Therefore  360 =  $\frac{1}{2}$ a ( 60 )²

Because time taken is one minute or 60 seconds

Therefore a = $\frac{360x2}{3600}$

or a = 0.2 m s⁻²
