A bullet of mass 50 g moving horizontally with a velocity 210 ms^(-1) gets embedded in a block of mass 1 kg kept on a rough horizontal surface. If the coefficient of kinetic friction between the block and surface is 0.5. The block- bullet system will move a distance of "______" before coming to res t(Acceleration due to gravity =10 ms^(-2)).

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

When the value of the frictional force is maximum, just before the body slides is called A. force of friction B. limiting force of friction C. compressive force friction D. Kinetic force of friction

The coefficient of static friction, mu_(s) between block A of mass 2 kg and the table as shown in the figure is 0.2. What would be the maximum mass value of block B so that the two blocks do not move? The string and the pulley are assumed to be smooth and massless. (g=10m//s^(2))

A block A with mass 100kg is resting on another block B of mass 200kg. As shown in figure a horizontal rope tied to a wall hold it. The coefficient of friction between A and B is 0.2 while coefficient of friction between B and the ground is 0.3 . the minimum required force F to start moving B will be.

Calculate the coefficient of static friction for an object of mass 50 kg placed on horizontal table pulled by attaching a spring balance. The force is increased gradually it is observed that the object just moves when spring balance shows 50N.

A block of mass m_(2) is placed on a horizontal table and another block of mass m_(1) is placed on top is it. An increasing horizontal force F = alpha t is exerted on the upper block but the lowwer block never moves as a result. If the coefficient of friction between the blocks is mu_(1) coefficient of friction between the blocks is mu_(1) and that between the lower block and the table is mu_(2), then what is the maximum possible value of mu_(1)//mu_(2) ?
