Question

If an object is moving at `3 m/s` and accelerates to `19 m/s` over 2 seconds, what was the object's rate of acceleration?

Answer 1

it is `8m/s^2`.

Explanation:

we can use the following formula for calculating the acceleration...

`a=(v-u)/t`

so...

`a=(19-3)/2`

which is equal to...

`8m/s^2` {in SI units}
