Two cars are moving in the same direction with the same speed `30 km//hr`. They are separated by a distance of `5 km`, the speed of a car moving in the opposite direction of it meets these two cars at an interval of `4` minutes, will be.

Two cars A and B are moving in same direction with velocities 30 m/s and 20 m/s. When car A is at a distance d behind the car B, the driver of the car A applies brakes producing uniform retardation of 2m//s^(2) . There will be no collision when :-

A car moving over a straight path, covers a distance d with constant speed of 40 km/hr and then the same distance with speed 60km/hr. The average speed of car is .....

Two cars A and B start moving from the same point with same velocity v=5km/minute. Car A moves towards North and car B in moving towards East. What is the relative velocity of B with respect to A ?

A car and a truck are moving with the same speed of 12ms^(-1) . If their masses are in the ratio 1:5 , find the ratio of their kinetic energy.

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?

A bird is tossing (flying to and fro) between two cars moving towards each other on a straight road. One car has a speed of 18 km/h while the other has the speed of 27 km/h. The bird starts moving from first car towards the other and is moving with the speed of 36 km/h and when the two cars were separated by 36 km. What is the total distance covered by the bird?

A bird is flying with a speed of 40 km/hr. in the north direction. A train is moving with a speed of 40km/hr. in the west direction. A passenger sitting in the train will see the bird moving with velocity:-

A car moving aling a straight highway with speed of 126 km h^(-1) is brought to a stop within a distance of 200 m . What is the retardation of the car (assumed uniform ) ans how doest it take fro the car to stop ?
