Two identical blocks A and B, each of mass \'m\' resting on smooth floor are connected by a light spring of natural length L and spring constant K, with the spring at its natural length. A third identical block (mass m) moving with a speed v along the line joining A and B collides with A. The maximum compression in the

A bag (mass M) hangs by a long thread and a bullet (mass m) comes horizontally with velocity v and gets caught in the bag. Then for the combined (bag + bullet) system

The relationship between force and position is shown in the figure given (in one dimensional case). The work done by the force in displacing a body from x = 1 cm to x = 5cm is

The pointer reading v/s load graph for a spring balance is as given in the figure. The spring constant is

Adjacent figure shows the force-displacement graph of a moving body, the work done in displaying body from x = 0 to x = 35 m is equal to

A 10 kg mass moves along x-axis. Its acceleration as a function of its position is shown in the figure. What is the total work done on the mass by the force as the mass moves from x = 0 to x = 8 cm

A toy car mass 5 kg moves up a ramp under the influence of force F plotted against displacement x. The maximum height attained is given by

The relation between the displacement X of an object produced by the application of the variable force F is represented by a graph shown in the figure. If the object undergoes a displacement from X = 0.5 m to X = 2.5 m the work done will be approximately equal to

The potential energy of a system is represented in the first figure. The force acting on the system will be represented by

A particle, initially at rest on a frictionless horizontal surface, is acted upon by a horizontal force which is constant in size and direction. A graph is plotted between the work done (W) on the particle, against the speed of the particle, (v). If there are no other horizontal force acting on the particle the graph would look like
