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.

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

The velocity of a car increase from 54 km/ hr to 75 km/hr. How much is the work done if the mass of the car is 1500 kg ?

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.

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?

A particle is moving with velocity 5 m/s towards east and its velocity changes to 5 m/s north in 10 s. Find the acceleration.

Starting from rest, a car movies with uniform acceleration and attains a velocity of 72 km hr^-1 in 20 s. It then moves with uniform speed for 25 s and is brought to rest in 10 s under uniform retardation. Find the total distance travelled using velocity-time graph.

The speed of a car is 60 (km)/(hour) . Find the distance covered by the car in 10 minutes,

A body moves with a velocity of 10 m/s for 10 s and then with a velocity of 20 m/s in the same direction for 40 s. Find its average velocity.
