A block of mass `10kg` is displaced by `10m` towards right by the application of force `F=20N`( 60 from horizontal ), as shown in the figure. The work done by the force is

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 2 kg is pulled through 3 m by a constnat horizontal force of 10N, along a frictionless horizontal table. What is the work doen by (i) the applied force and (ii) the gravitational force?

Two blocks of masses 10 kg and 20 kg are connected by a massless string and are placed on a smooth horizontal surface as shown in the figure. If a force F=600 N is applied to 10 kg block, then the tension in the string is

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.

If the mass of block is 1 kg and a force of 10 / sqrt3 N is applied horizontally on the block as shown in the figure . The frictional force acting on the block is :

A 5 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with position as shown in the figure. Find the work done by this force as the block moves from the origin to x = 8m.

A block of mass sqrt(3)//10kg is placed on a rough horizontal surface as shown in the figure. A force of 1N is applied at one end of the block and the block remains stationary. The normal force exerted by the sruface on the block acts(g=10 m//s^(2) )

A plank of mass 10 kg and a block of mass 2 kg are placed on a horizontal plane as shown in the figure. There is no friction between plane and plank. The coefficient of friction between block and plank is 0.5 .A force of 60 N is applied on plank horizontally. In first 2 s the work done by friction on the block is
