String Mass System and Friction

For the arrangement shown in figure when the system is released, find the acceleration of wedge. Pulley and string are ideal and friction is absent.

Two bodies of masses 4 kg and 6 kg are tied to the ends of a massless string. The string passes over a frictionless pulley. The acceleration of the system is :

If coeffiecient of friction between the block of mass 2kg and table is 0.4 then out acceleration of the system and tension in the string. (g=10m//s^(2))

The friction coefficient between plank and flooe is mu . The man applies, the maximum possible foce on the string and the system remains at rest. Then

A rod of mass m is supported by string AB and friction due to wall. Then friction force on rod due to wall is : (g= acceleration due to gravity )

An arrangement of the masses and pulleys is shown in the figure. Strings connecting masses A and B with pulley are horizontal and all pulleys and strings are light. Friction coefficient between the surface and the block B is 0.2 and between block A and B is 0.7 . The system is released from rest. (use g=10m//s^(2))

The given figure shows a small mass connected to a string which is atteched to a string , which is attached to a vertical post. If the mass is released from rest when the string is horizontal as shown the magnitude of the total acceleration of the mass as friction of the angle theta is

In Fig. 6-43, a 15 kg sled is attached to a 2.0 kg sand box by a string of negligible mass, wrapped over a pulley of negligible mass and friction. The coefficient of kinetic friction between the sled and table top is 0.040. Find (a) the acceleration of the sled and (b) the tension of the string.

A bullet of mass A and velocity B is fired into a block of wood of mass C. If loss of any mass and friction be neglected, the velocity of the system must be
