A 2 kg block of wood rests on a long table top. A 5 g bullet moving horizontally with a speed of `150 ms^(-1)` is shot into the block and sticks to it. The block then slides 2.7m along the table top and comes to a stop. The force of friction between the block and the table is

A bullet of mass 10 g moving horizontally with a speed of 400 m//s a block of mass 390 g and remains in it. The block slides 10 m on rough surface before coming to rest. The friction coefficient is

A 4g bullet is fired horizontally with a speed of 300 m/s into 0.8kg block of wood at rest on a table and gets embedded in the block. If the coefficient of friction between the block and the table is 0.3, how far will the block slide approximately ?

A block on table shown in figure is just on the wedge of slipping. Find the coefficient of static friction between the block and table top.

A block A of mass m_1 rests on a horizontal table . A light string connected to it passes over a frictionless pulley at the edge of table and from its other end another block B of mass m_2 is suspended . The coefficient of kinetic friction between the block and the table is mu . When the block A is sliding on the table the tension in the string is :

A horizontal force of 20 N is applied to a block of mass 4 kg resting on a rough horizontal table. If the block does not move on the table, how much frictional force the table is applying on the block. What can be said about the coefficient of static friction between the block and the table? Take g=10m/s^2 .
