Homework Help: Physics

Posted by Hannah on Saturday, June 20, 2009 at 8:55pm.

A racecar driver in an 825-kg car accelerates from rest to a velocity of 21.5 m/s in 0.55 s. What is the net force acting on the car?

I found out using A=v/t that the horizontal acceleration is 39.1 m/s^2. My problem now is this...

Is the net force just F=ma? Or do I have to take account for gravity and somehow find the vector sum???
