1. The problem statement, all variables and given/known data A car of mass 1000 kg accelerates on a straight, flat, horizontal road with an acceleration a = 0.3 m s-2 . The driving force F on the car is opposed by a resistive force of 500 N. What is the net (resultant) force on the car? 2. Relevant equations F=ma 3. The attempt at a solution 0.3*1000= 300N 500N- 300N= 200N answer is 300N... Why?
