Question: 1. At 2 0 seconds the driver steps on the brake pedal so that the net force on the car is 2 5 0 0

  
1. At 20 seconds the driver steps on the brake pedal so that the net force on the car is 2500N forward.
a. How much time (After the 20 seconds) does the car take to stop?
 
b. How far does the car travel (After the 20 seconds) until it reaches a stop? 
 
2. The man gets out of the car. Because the car is out of gas, he pushes backward on the car with a constant force of 500N.
 
  What is the acceleration of the car when the man is pushing on it?
