(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If the rider stops pedalling calculate the distance traveled by the bicycle before it comes to rest from an initial speed of 2m/s.

Mass of rider: 60kg

Mass of bicycle: 7 kg

Drag: 7.5 V^2 (where V is the velocity)

Slope : 10°

3. The attempt at a solution

F= ma

-7.5V^(2) - sin10° mg = ma to find the deceleration

however I know that the drag decreases with the decrease in velocity, hence the deceleration is not constant! I think I should use some sort of integral! HELP!!!!

sorry guys I found the formula I was looking for derived by my lecturer!!
