Homework Help: physics

Posted by Jeon on Friday, September 2, 2011 at 11:52am.

Lauren was driving north on Hwy 75 with a speed of 46.7 m/s when she heard on a CB that a patrolman was hiding 112.7 m north of where she is. Knowing that the patrolman can start clocking the car in 2.9 seconds, Lauren decided to slow to 27.5 m/s. and immediately pressed on the brakes. Assuming that the overall mass of the car with its occupants is 1102 kg and that the acceleration of the car while it is slowing is -6.6 m/s2, what is in Newtons the net force acting on the car while it is slowing down? (don't include units in your answer and use North as the positive direction
