Answer #1

The applied force F = 255 N. And the mass of the car is m = 500 kg. So, the acceleration of the car is
     
The time of travel is t = 18.3 s.
So, kinematical equation, if the car starts from rest (initially the car was stationary), then the distance travelled in time t is
  
So, putting the given values, we get
  
  

So, option (a) is correct.
