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?

Respuesta :

Cantor

Answer:

Δt = 2.47 s

Explanation:

The problem involves just the formula of the acceleration:

[tex]a = \frac{Δv}{Δt} [/tex]

[tex]Δv = (27.7 - 0) \: m/s[/tex]

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

[tex]Δt = Δv/a[/tex]

Δt = 2.47 s
