A man goes on a straight path from `A` to `B` with speed `10m/s` and comes back with speed `20m/s`. Then average velocity and average speed will be....

What is the significance of average velocity or average speed?

A boy goes to a school from his home at a speed of x km/hr and comes back at a speed of y km/hr, then the average speed is given by

A motorcyclist drives from A to B with a uniform speed of 30 km h^(-1) and returns back with a speed of 20 kmh^(-1) . Find its average speed.

A man travels 200 km distance with the speed of 40 m/s and next 50 km with the speed of 10 m/s . Find the average speed of man.

Consider an 1100 particels gas system with speeds distribution as follows : 1000 particles each with speed 100 m//s 2000 particles each wityh speed 200 m//s 4000 particles each with speed 300 m//s 3000 particles each with speed 400 m//s and 1000 particles each with speed 500 m//s Find the average speed, and rms speed.

Distinguish between average speed and average velocity.

A car moves a distance of 100 m. It coveres first half with speed of 10 m/s and another half with speed of v m/s. If the average speed of car is 18 m/s, then value of v is

A car runs at a constant speed on a circulat track of radius 100 m . Taking 62.8 s for every circular lap. The average velocity and average speed for each circular lap respectively are :

Find average speed of 40m/s and 50m/s.

A man 'A' moves in north direction with speed 10m/s and another man B moves in E-30^(@)-N with 10 m//s . Find the relative velocity of B w.r.t. A.
