Science
Thanks again for the help, I am now getting there with my assignment. Just one more question though. If I doubled the weight of the car, would the deceleration rate change from 6m/s to 12m/s?

Science
Thanks for your reponse, it helped greatly. Can you please also tell me if the braking distance is 24metres and it decelerates at rate of 6m/s, does that mean that the time taken to stop after braking would be 4 seconds or do I need to consider anything else to calculate time.
