1. The problem statement, all variables and given/known data Hey new to forum here.... Grade 11 physics student... Love physics and math!!!! But this one question seems easy but I can't seem to get through... Here it is : A 1100kg car accelerates at 3.40 m/s. If the wheels exert a force of 5600N on the road, calculate the force of friction resisting the motion? 2. Relevant equations F net= m x a ... But I don't which equation to use.. I know friction is normally calculated with F fr = u * Fn 3. The attempt at a solution I have the answer... But don't know where to start other than maybe finding the net force..
