Question

A car advertised states that it can accelerate from rest to 70 m/s in 7 seconds. What is its acceleration?

Answer 1

10
`m/s^(2)`

Step-by-step explanation:

Formula to find acceleration is :

Acceleration =
`(ChangeInVelocity)/(TIme)`

OR

Acceleration =
`(Final velocity-Initial velocity)/(Time)`

=
`(70 - 0)/(7)`

=
`(70)/(7)`

= 10
`m/s^(2)`
