I'm working on a problem for physics in which I found the resultant of two forces on a car (770 Newtons) and the car weighs 3000 kg. I put it in the formula F=ma so it looked like 770N=3000kg*A and I don't know if you can divide those two units by each other to get acceleration. Thanks for any help

The Newton is a SI unit which is defined by; 1Newton is the force needed to cause an acceleration of 1m/s^2 on an object with 1kg of mass.

So yes, by its definition, Newtons divided by mass would give accleration.

Right - in fundamental terms, 1 Nt = 1 kg-m/s^2. You should memorize that - it comes up a lot in physics.

One newton (on Earth surface) is equal to:-
