Consider the situation shown in figure. All the surfaces are frictions and the string and the pulley are light. Find the magnitude of the acceleration of the two blocks.

find the acceleration of the block of mass M in the situation shown in figure. All the surfaces are frictionless and the pulleys and the string are light.

Two blocks of masses 3 kg and 6 kg are connected by a string as shown in the figure over a frictionless pulley. The acceleration of the system is

Two masses of 8 kg and 4 kg are connected by a string as shown in figure over a frictionless pulley.The acceleration of the system is

In the system shown in fig the pulley is frictionless and the string massless if m_(1)=m_(2) thrust on the pulley will be:

A string is would over a cylinder of mass M, radius R and moment of inertia I and then the string is would over the pulley as shown in the figure. If the system is released from rest then determine the tension is tring. Assume there is no slipping between string and pulley cylinder.

Consider the situation shown in the figure. The surface is smooth and the string and the pulley are light. Find the acceleration of each block and tension in the string.
