4.4 Newton's Third Law of Motion


A car weighs 2,000 kg. It moves along a road by applying a force on the road with a parallel component of 560 N. There are two passengers in the car, each weighing 55 kg. If the magnitude of the drag experienced by the car is 45 N, what is the acceleration of the car?

  1. 0.244 m/s2
  2. 0.265 m/s2
  3. 4.00 m/s2
  4. 4.10 m/s2
