A block of weight `15N` slides on a horizontal table the co-efficient of siliding fricition is `0.4`. The area of the block in contact with the table is `0.5m^(2)`. The shearing stress will be

A block of mass 1kg is at rest on a horizontal table. The coeficient of static friction between the block and the table is 0.5 . The magnitude of the force acting upward at an angle of 60^(@) from the horizontal that will just start the block moving is.

A block of mass 1kg lies on a horizontal surface in a turck, the coefficient of static fricition between the block and the surface is 0.6, what is the force of fricition on the block. If the acceleration of the truck is 5m//s^(2) .

A block of mass 1kg lies on a horizontal surface in a turck, the coefficient of static fricition between the block and the surface is 0.6, what is the force of fricition on the block. If the acceleration of the truck is 5m//s^(2) .

In the figure shown, a block of weight 10 N resting on a horizontal surface. The coefficent of static friction between the block and the surface mu_(s)=0.4 . A force of 3.5 N will keep the block in uniform motion, once it has been set in motion. A horizontal force force of 3N is applid to the block, then the block will

A block of mass 4 kg is resting on a horizontal table and a force of 10 N is applied on it in the horizontal direction. The coefficient of kinetic friction between the block and the table is 0.1. The work done in sqrt(20) s

A block of mass 15kg is placed on a long trolley. The cofficient of fricition between the block and trolley is 0.18. The trolley accelerates from rest with 0.5m//s^(2) for 20s. then what is the friction force:-
