Question

Calculate the aceleration of a vehicle if the initial velocity (Vi) is 20 m/s and acelerates to 40 m/s (V) in 3,8 s. (t).

Answer 1

Huh? What do u say!

Step-by-step explanation:

Answer 2

Hello!!

For calculate the aceleration of the vehicle let's applicate formula:

`\boxed{V=V_i + a*t}`

`\textbf{Being:}`

`\sqrt{}` V = Final velocity = 40 m/s

`\sqrt{}` Vi = Initial velocity = 20 m/s

`\sqrt{}` a = Aceleration = ?

`\sqrt{}` t = Time = 3,8 su

⇒
`\text{Then let's \textbf{replace it according} we information:}`

`40 \ m / s = 20 \ m / s + a * 3,8 s`

⇒
`\text{We clear the`

`a = (40 \ m /s - 20 \ m / s )/(3,8 \ s)`

⇒
`\text{Let's resolve it: }`

`a = 5,263 \ m / s`

`\textbf{Result:}\\\text{The aceleration is of \textbf{5,263 m/s}}^(2)`
