- Stopping distance is calculated as:
- Stopping Distance = Reaction Time Distance + Braking Distance
- Braking distance is the distance traveled after you apply the brakes. It depends on two factors: speed and drag.
- Drag factors
- The drag factor is a measure of the friction between the snowmobile’s track and the surface it travels over.
- Deep, powdery snow stops snowmobiles more quickly because it creates more drag than shallower snow.
- Glare ice has less drag than deep snow, so snowmobiles travel much farther after braking.
The graph gives example stopping distances at various speeds. Note that your stopping distance could be different due to your reaction time and track conditions.
