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

Explanation:

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

S = u t + a t²

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

Thus S =   a t²

here S is displacement and a is the acceleration of car

Therefore  360 =   a ( 60 )²

Because time taken is one minute or 60 seconds

Therefore a =

or a = 0.2 m s⁻²

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
