## Homework Statement

Ten seconds after starting from rest, a car with a mass of 1000kg is moving at 40m/s. The acceleration of the car is?

## Homework Equations

F=ma or a=vf-vi/t

## The Attempt at a Solution

I have m=1000kg

t=10s

d=40m/s

I am not sure if d is 40m/s though or is the force?

And with one of the formulas I picked I wouldn't be able to use 1000kg? I have a feeling that this problem requires two formulas.
