Stopping distance of vehicles : When brakes are applied to a moving vehicle, the distance it travels before stopping is called stopping distance. It is an important factor for road safety and depends on the initialy velocity (v_(0)) and the braking capacity, or deceleration -a that is caused by the braking. Derive an expression for stopping distance of a vehicle in terms of v_(0) and a .

The minimum stopping distance of a car moving with velocity u is x . If the car is moving with velocity 2v, then the minimum stopping distance will be.

If the speed of a car increases 4 times, the stopping distance ( in m) for this will increase by _________ .

An automobile travellingat 40 km//h , can be stopped at distance of 40 m by applying brakes. If the same autombile is travelling at 80 km//h , the minimum stopping distance, in metres is (assume no skidding) :

The minimum stopping distance on level ground is 5 m for a vehicle moving at 10 m/s if the same vehicle is going down an incline of inclination 37^(@) . What is the minimum stopping distance ?

A car moving with a speed of 40 km//h can be stopped by applying the brakes after at least 2 m. If the same car is moving with a speed of 80 km//h , what is the minimum stopping distance?
