A box, heavier than you is placed on a rough floor. The coefficient of static friction between the box and the floor is the same as that between your shoes and the floor. Can you displace the box across.the floor.

A man pulls a block of mass equal to himself with a light string .The coefficient of friction between the man and the floor is greater than that between the block and the floor

A horizontal force F pulls a 20 kg box at a constant speed along a rough horizotal floor. The coefficient of friction between the box and the floor is 0.25. The work done by force F on the block in displacing it by 2 m is

A block of mass m is placed on a rough floor of a lift . The coefficient of friction between the block and the floor is mu . When the lift falls freely, the block is pulled horizontally on the floor. What is the force of friction -

In Fig. 7.149 , coefficient of friction between the block and the floor is mu . Force F that will move the block on the floor with a uniform speed is :

You want to apply a force on a box so that it moves with constant speed across a horizontal floor. The coefficient if kinetic friction between the box and the floor is mu_(k). Of the flur following cases, the force you apply on the box will be smallest when you

A body of mass M is applying horizontal force to slide a box of mass M_(1) on a rough horizontal surface The coefficient of friction between the shoe of the boy and the floor is mu and that between the box and the floor is 'mu_(1)' In which of the following cases is it certainly not possible to slide the box ? .

A horizontal force F pulls a 20 kg box at a constant speed along a horizontal floor. If the coefficient of friction between the box and the floor is 0.25,how much work is done by the force F in moving the box through a distance of 2 m?

A man of mass 75 kg is pushing a heavy box on a flat floor. The coefficient of kinetic and static friction between the floor and the box is 0.20 , and the coefficient of static friction between the man's shoes and the floor is 0.80 . If the man pushes horizontally, what is the maximum values (in kg ) of the box he can move?
