A car A is travelling on a straight level road with a uniform speed of 60 km/h. It is followed by another car B which in moving with a speed of 70 km/h. When the distance between then is 2.5km, the car B is given a deceleration of `20km//h^2`. After how much time will B catch up with A

A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. The total distance covered by the car is:

A car is moving with a speed of 54 km//h . What will be the kinetic energy of the boy of mass 40 kg sitting in the car ?

A car moving along a straight line at a speed of 72km/h stops in 5s. After the brakes are applied. Find the acceleration

A car takes 2 hours to reach a destination by travelling at the speed of 60 km/h. How long will it take when the car travels at the speed of 80 km/h?

A car travels 30 km at a uniform speed of 40 km/h and the next 30 km at a uniform speed of 20 km/h . Find its average speed.

In each of the following problems, clearly state what the relevant and irrelevant factors are while going through Steps 1, 2 and 4 given in this chapter :- Suppose a car starts from a place A and travels at a speed of 40 km/h towards another place B. At the same instance, another car starts from B and travels towards A at a speed of 30 km/h. If the distance between A and B is 100 km, after how much time will the cars meet?
