A block of mass m, lying on a smooth horizontal surface, is attached to a spring (of negligible mass) of spring constant k. The other end of the spring is fixed, as shown in the figure. The block is initally at rest in its equilibrium position. If now the block is pulled withe a constant force F, the maximum speed of the block is :

Two blocks of mass m and 2m are kept on a smooth horizontal surface. Theya are connected by an ideal spring of force constant k. Initially the spring is unstretched. A constant force is applied to the heavier block in the direction shown in figure. Suppose at time t displacement of smaller block is x_(1) then displacement of the heavier block at this moment would be

A bullet of mass m embeds itself in a block of mass M resting on a smooth horizontal surface, attached to a spring of force constant k. If the initial speed of the bullet is v_(0) along horizontal, find (a) the maximum compression of the spring and (b) the time for the bullet - block system to come to rest.

A block of mass m moving with velocity v_(0) on a smooth horizontal surface hits the spring of constant k as shown. The maximum compression in spring is

A block of mass m is initially moving to the right on a horizontal frictionless surface at a speed v. It then compresses a spring of spring constant k. At the instant when the kinetic energy of the block is equal to the potential energy of the spring, the spring is compressed a distance of :

A block of mass m is connected to another .block of mass M by a massless spring of spring constant k. A constant force f starts action as shown in figure, then:

A block of mass m lies on a horizontal frictionless surface and is attached to one end of a horizontal spring (with spring constant k ) whose other end is fixed . The block is intinally at rest at the position where the spring is unstretched (x=0) . When a constant horizontal force vec(F) in the positive direction of the x- axis is applied to it, a plot of the resulting kinetic energy of the block versus its position x is shown in figure. What is the magnitude of vec(F) ?

A block of mass m is connected with another block of mass 2m kept on a rough horizontal table by means of an ideal spring of spring constant K and a massless string as shown in the figure. The minimum coefficient of friction between the block of mass 2m and the table so that the block does not slide, when block of mass m is suddenly released, is

Two blocks each having mass m is attached to each other with a spring having force constant k. The system is placed on a rough horizontal surface having coefficient of friction mu . The maximum initial compression, that can be given to the spring so that when released the blocks do not move is
