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.
