According to a FIR in police station, car A was at rest waiting for a red light at a crossing when it was hit by similar car B from rear side. Both cars had then hard brekes on, and from their skid marks it is surmiesed that they skidded together about 8m in the original direction of travel before coming to rest. Assuming a stopping force of about 0.4 times the combined weights of the cars. the speed of car B just before the collision is approximately `[g=10 m//s^(2)]`

Accordingto a FIR in police station, car A wassittingat rest waiting for a red light at a crossing when it was hit by an identical car B from rear side. Bothcars had their hand brakes on, and from their skid marks it is surmised that they skidded together about 6 m in the oriinal directionof travel before coming to reat. Assuming a stopping force of about 0.7 times the combined weights of the cars (that is, mu=0.7 ) what must have been the approximate speed of car B just before the collision ?

A car travelling at a speed of 54 km/hr is brought to rest in 90 s. Find the distance travelled by the car before coming to rest.

A car is travelling at the rate of 70 km/hr. Suddenly the brakes are applied causing all the tyres to skid. How far will the car travel before coming to rest ? Given mu = 0.2.

Most of the skid mearks left at the scence of an automobile accident are left by the car tires after the collision occurs. How can measuring the direction and length of these skid marks. After the collision reveal whether either of the cars involved was speeding before the collision?

A car is travelling at 30 km/h in a circle of radius 60 m. What is the minimum value of mu_(s) for the car to make the turn without skidding ?

Initially a car is moving with speed of 20 ms^(-1) and covers a distance of 100 m before it comes to rest. On making the initial speed of car 40 ms^(-1) keeping the acceleration same, the distance travelled by car before it comes to rest is

Initially a car is moving with speed of 20 ms^(-1) and covers a distance of 100 m before it comes to rest. On making the initial speed of car 40 ms^(-1) keeping the acceleration same, the distance travelled by car before it comes to rest is

Starting from rest a car moves for sometime with a constant acceleration x and then with a constant retardation y and finally it comes to rest. If the car is in motion for a total time t, the maximum velocity of the car is

A car starts from rest in a circular flat road of radius R with an acceleration a. The friction coefficient between the road and the tyred is mu Find the distance car will travel before is start skidding.

The brakes of a car moving at 20 m/s along a horizontal road are suddenly applied and it comes to rest after travelling some distance if the coefficient of friction between the tyres and the road is 0.90 and it is assumed that all four tyres behave identically, the shortest distance the car would travel before coming to a stop is
