A block of mass 2 kg is plased on a smooth horizontal surface. Two forces F_(1)=20 N and F_(2)=5 N start acting on the block in opposite directions as shown. If block gets displaced by 5 m in the direction of net force then work done by F_(2) is :-

Two blocks A and B each of mass m are placed on a smooth horizontal surface. Two horizontal force F and 2F are applied on blocks A and B, respectively, as shown in fig. Block A does not slide on block B. Then then the normal reaction acting between the two blocks is (assume no friction between the blocks)

A block of mass 10 kg is placed on a horizontal surface as shown in the figure and a force F = 100 N is applied on the block as shown, in the figure. The block is at rest with respect to ground. If the contact force between block and ground is 25n (in Newton) then value of n is : (Take g = 10 m//s^(2))

A block of mass 10 kg is placed on the rough horizontal surface. A pulling force F is acting on the block which makes an angle theta above the horizontal. If coefficient of friction between block and surface is 4/3 then minimum value of force required to just move the block is (g = 10 m/s^2)

A block of mass M is kept on as rough horizontal surface. The coefficient of static frictionbetween the block and the surface is mu . The block is to be pulled by applying a force to it. What minimum force is needed to slide the block? In which direction should this force act?

Two blocks of masses 1 kg and 2 kg are placed in contact on a smooth horizontal surface as shown in fig. A horizontal force of 6N is applied d(a) on a 1-kg block. Find the force of interaction of the blocks. .

Two blocks of masses 7 kg and 3 kg are connected by a spring of stiffness 1000Nm^(-1) and placed on a smooth horizontal surface. They are acted by horizontal forces of 72 N and 32 N in opposite directions as shown in the figure. When accelerations of the blocks are equal and constant, the extension of the spring is
