7.If "50m" is the distance at which a car can be stopped when initially it was moving with speed "10ms^(-1)",then on making the speed of the car "50ms^(-1)",the distance at which the car can be stopped is (retardation is same in both cases)

If x is the distance at which a car can be stopped when initially it was moving with speed u, then on making the speed of the car Nu, the distance at which the car can be stopped is

Tripling the speed of the motor car multiplies the distance needed for stopping it by

Consider a car moving on a straight road with a speed of 100m//s . The distance at which car can be stopped is [mu_k=0.5]

The driver of a car moving with a speed of 10 ms^(-1) sees a red light ahead, applies brakes and stops after covering 10 m distance. If the same car were moving with a speed of 20 ms^(-1) the same driver would have stopped the car after covering 30 m distance. Within what distance the car can be stopped if traveling with a velocity of 15 ms^(-1) Assume the same reaction time and the same deceleration in each case

A car is moving along a straight horizontal road with a speed v_(0) . If the coefficient of friction between the tyre and the road is mu, the shortest distance in which the car can be stopped is.
