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? Thanks.
