A block of mass 1 kg is held at rest against a rough vertical surface by pushing by a force F horizontally. The coefficient of friction is 0.5. When

A block of mass m is placed on the top of another block of mass M as shown in the figure. The coefficient of friction between them is mu . The maximum acceleration with which the block M may move so that m also moves along with it is

A block of mass m is placed behind in contact with vertical side of M as shown in the figure. The coefficient of static friction between m and M in mu . The least horizontal force with which m can be pushed so that the two blocks move together is (neglect friction between M and ground).

A spring, placed horizontally on a rough surface is compressed by a block of mass m, placed on the same surface so as to store maximum energy in the spring. If the coefficient of friction between the block and the surface is mu , the potential energy stored in the spring is

A disc of radius 5 m is rotatating with angular frequency 10 rad/sec. A block of mass 2 kg is to be put on the disc frication coefficient between disc and block is mu_(K)= 0.4 , then find the maximum distance from axis where the block can be placed without slidding:

A block of mass m is placed at rest on an inclination theta to the horizontal. If the coefficient of friction between the block and the plane is mu , then the total force the inclined plane exerts on the block is

A block is released from rest from point on a rough inclined place of inclination 37^(@). The coefficient of friction is 0.5.
