Question #0ef3c

Answer 1

`a = 4 (m)/(s^2)`

Explanation:

Since acceleration is described as a change in velocity over change in time, then we can do the following

`color(white)(-----)color(magenta)(a = (v_(f)-v_(i))/(Deltat)`

We know the following

`Deltat = 2" s"`
`v_(i) = 0" m/s"`
`v_(f) = 8" m/s"`

Now, plugin

• `color(magenta)(a = (v_(f)-v_(i))/(Deltat)`

• `a = ((8 m/s)-(0 m/s))/(2" s")`

• `color(blue)(a = 4 (m)/(s^2)`

`color(blue)("Answer" = a = 4 (m)/(s^2)`
