What is the average friction force when a person has a usual 1 km walk?

What is the average speed of the car if it covers 200 km in 5 h?

The mass of a car is 1200 kg. It comes to rest due to retardation of 2 ms^(-2) . What would be the force (frictional force) acting between the car and road ?

Assertion :- When a man climbs the rope friction force acts in downward direction. Reason :- Friction force opposes relative motion to tendency of relative motion between two contact surfaces.

A block of mass 0.1 is held against a wall applying a horizontal force of 5N on block. If the coefficient of friction between the block and the wall is 0.5, the magnitude of the frictional force acting on the block is:

TV transmission tower at Kota has a height of 80 m. Radius of earth is 6400 km (i) What is its coverage range (ii) How much population is covered by transmission if the average population density around the tower is 2000 km^(-2) ?

Coefficient of friction between 5 kg and 10 kg block is 0.5 . If friction between them is 20 N . What is the value of force being applied on 5 kg ? The floor is frictionless

Avinash is moving with the velocity 8ms^(-1) against the frictional force 10 N acting on him and Kapil is moving with the velocity 3ms^(-1) against the frictional force 25 N acting on him. Whos power would be more?
