How long does it take to stop a car going 25 mph?
Reaction Distance = Speed, Calculate Stopping Distance: Therefore, if you are driving 25 mph, it will take you approximately 56.25 feet to stop your car.

| 20mph | 12 Meters / 40 Feet |
| 30mph | 23 Meters / 75 Feet |
| 40mph | 36 Meters / 118 Feet |
| 50mph | 53 Meters / 175 Feet |
How many feet will it take to stop from 60mph?
Driver Care – Know Your Stopping Distance

Does mass affect stopping distance?
If you can make your tires skid, mass does not really affect stopping distance. This is another way of saying the limiting factor is road/tire friction. Thus max stopping force increases proportionally with mass and balances the F=ma equation.
Why does braking distance increase with mass?
This increases friction. So vehicles with more mass have more friction against the ground, which decreases stopping distance. Conclusion: Vehicles with more mass have more momentum, which increases stopping distance.
Does car weight affect stopping distance?
The distance required to stop a vehicle depends on its speed and weight in addition to the factors of energy, heat and friction. For example, if weight is doubled, stopping power must be doubled to stop in the same distance. If speed is doubled, stopping power must be increased four times to stop in the same distance.
