This is probably horribly easy, but it's almost 1 AM so I'm going nutty trying to figure this one out.(adsbygoogle = window.adsbygoogle || []).push({});

The questoni: "A 2000kg car is traveling at a constant 30m/s with the motor producing a force of 4000 N forward. Find the force of friction."

I drew the diagram. Is acceleration 0?

I'd appreciate any help. Thank you~
