Two blocks A and B are connected by a massless string (shown in figure) A force of 30 N is applied on block B. The distance travelled by centre of mass in 2s starting from rest is :

Two blocks of masses 2 kg and 4 kg are connected by a massles string which is just taut. Now two forces 3 N and 14 N are applied on blocks. The tension in the string is

Figure shows two blocks connected by a light inextensible string as shown in figure. A force of 10 N is applied on the bigger block at 60^(@) with horizontal, then the tension in the st ring connection the two masses is -

Figure shows two blocks connected by a light inextensible string as shown in figure. A force of 10 N is applied on the bigger block at 60^(@) with horizontal, then the tension in the st ring connection the two masses is -

Two blocks A & B are connected by the massless string & pulley. As the blocks are left to move, the force by the pulley on the clamp is

Two blocks A and B of equal mass m are connected through a massless string and arranged as shown in figure. Friction is absent everywhere. When the system is released from rest:

Three blocks are connected by massless strings on a frictionless inclined plane of 30^(@) as shown in the figure. A force of 104 N is applied upward along the incline to mass m_(3) causing an upward motion of the blocks. What is the acceleration of the blocks? (Assume, acceleration due to gravity, g=10 m//s^(2) )

A system of two blocks A and B are connected by an inextensible massless string as shown in Fig. The pulley is massless and frictionless. Initially, the system is at rest. A bullet of mass 'm' moving with a velocity 'u' as shown hits block If and gets embedded into it. The impulse imparted by tension force to the block of mass 3m is
