Ana's car has a dead battery. She and 4 of her friends push the car closer to get help. The mass of the car with Ana inside is 1100 kg. Ana steers straight ahead while each of her four friends applies a 120 N force to the back of her car. If the car accelerates at 0.3 m/s2, what is the resistive force of friction that the friends are pushing against?
