The velocity of a car increases from 54 km/hr to 72 km/hr. How much is the work done if the mass of the car is 1500 kg?

Solve the following examples: The velocity of a car increases from 54 km//h to 72 km//h . If the mass of the car is 1500 kg, find the work done to increase the velocity.

The velocity of a car decreases from 43 (km)/h to 25 (km)/h in 10 s. Find its retardation.

The velocity of a car increases from 15 (km)/h to 33 (km)/h in 20 s. Find its acceleration.

Mass of a vehicle is 1500 kg. While ascending on a road, its speed decreases from 72 km/hr to 36 km/hr. How much is the work done?

In a certain time interval, the velocity of a car reduces from 72 km/h to 36 km/h. If the car covers a distance of 150 m during this time interval, find the retardation of the car.

A train approaching a station reduces its speed from 180 km/hr to 90 km/hr. If the mass of the train is about 20,000 kg then how much is the work done by the train?

The critical velocity of a satellite of mass l 00 kg is 20 km/hr. The critical velocity of another satellite of mass 200 kg in the same orbit is

A car travels 48 km in 50 minutes. How much time will it take to travel 24 km at the same speed?

An aeroplane A, is travelling in a straight line with a velocity of 300 km/ hr with respect to Earth . Another aeroplane B, is travelling in the opposite direction with a velocity of 350 km/hr with respect to Earth. What is the relative velocity of A with respect to B? What should be the velocity of a third aeroplane C moving parallel to A, relative to the Earth if it has a relative velocity of 100 km/hr with respect to A?
