Question

A certain sports car can accelerate from 0 m/s to 27.7 m/sec with an acceleration of 11.2 m/s². How long does this acceleration take in seconds?

Answer 1

Δt = 2.47 s

Step-by-step explanation:

The problem involves just the formula of the acceleration:

`a = (Δv)/(Δt)`

`Δv = (27.7 - 0) \: m/s`

You want to know Δt, knowing the time and the speed. So:

`Δt = Δv/a`

Δt = 2.47 s
