How to calculate vehicle deceleration (time to stop)

  1. Ok here is my question. Take a person riding a bike. If you can calculate their momentum by knowing their total weight and speed, how could you calculate the DISTANCE they will roll if they stop pedalling and apply no force. Assume that there is absolutely no wind at the time. And add in a grade to the road, expressed in vertical distance divided by road length (hypotenuse of triangle).

    What equations would you use, and how would you calculate it?

    Well,if it's climbing up an incline,you can use simple kinematics.If the wheels are rolling and there's no friction,i assume the tangential component of gravity will slow the bike down to eventual stopping.

    So simply use the kinematics on an incline.
