I need a formula(s)!!!(adsbygoogle = window.adsbygoogle || []).push({});

I have a vehicle(semi) traveling on a 2% downgrade with a begnining speed of 60mph, no acceleration or braking on the downgrade. Adj "f" is .73 if that is needed. I need to be able to calculate the vehicles increase in speed in both time and distance increments. Doesn't matter what the incriments are, 20ft, 100ft or every 10sec of travel, it doesnt' matter.
