Question

A car can accelerate from rest to 28 m/s and travels 280meters. How long does this acceleration take?

Answer 1

`a=1.4m/s^2`

Step-by-step explanation:

From the question we are told that

Velocity v=28m/s

Distance d=280

Generally the Newtons equation for motion is mathematically given as

Acceleration

`v^2=2as`

`a=(V^2)/(2s)`

`a=(28^2)/(2*280)`

`a=1.4m/s^2`
