A block of mass m rests on top of a block of mass 2m which ls kept on a table. The coefficient of kinetic friction between all surfaces is `mu = 1 A` massless string is connected to each mass and wraps halfway around a massless pulley, as shown. Assume that you pull on the pulley with a force of 6 mg. What ls the acceleration of your hand ?

A block of mass m is kept on a horizontal table. If the static friction coefficient is mu ., find the frictional force acting on the block.

In the shown mass pulley system, pulleys and string are massless. The one end of the string is pulled by the force F = mg. The acceleration of the block will be :

A block of mass m = 2kg is accelerating by a force F = 20N applied on a smooth light pulley as shown in the figure. If the coefficient of kinetic friction between the block and the surface is mu=0.3 , find its acceleration.

A block of mass M is being pulley along horizontal surface .The coefficient of friction the block and the surface is mu If another block of mass M//2 is placed on the block and it is pulled is again pulled on the surface , the coefficient of friction the block and the surface will be

In the shown mass pulley system, pulleys and string are massless. The one end of the string is pulleed by the force F=2mg . The acceleration of the block will be

Two blocks of masses M and m are connected with massless and frictionless pulleys as shown. Strings are also massless. If the magnitude of acceleration of M is a_(0) then magnitude of acceleration of m is

A block of mass m is placed on a rough horizontal surface. If minimum force to pull the block is (mg)/(2) then coefficient of friction is :

Block B of mass m_(B) = 0.5 kg rests on block A, with mass m_(A) = 1.5kg which in turn is on a horizontal tabletop (as shown in figure) .The coefficient of kinetic friction between block A and the tabletop is mu_(k) = 0.4 and the coefficient of static friction between block A and blockB is mu_(s) = 0.6 A light string attached block A passes over a frictionless, massless pulley and block C is suspeneded from the other end of the string. What is the largest mass m_(c) (in kg) that block C can have so that block A and B still slide together when the system is relaced from rest?

A wooden block of mass m resting on a rough horizontal table is pulled by a force F as shown in the figure. If mu is the coefficient of friction between block and table, its acceleration will be
