A block is suspended by an ideal spring of force constant k. If the block is pulled down by applying a constant force F and if maximum displacement of the block from its initial position of rest is `delta`, then

A block is suspended by an ideal spring of force constant force F and if maximum displacement of block from its initial mean position of rest is x_(0) then

Two blocks of masses m_(1) and m_(2) are connected by an ideal sprit, of force constant k . The blocks are placed on smooth horizontal surface. A horizontal force F acts on the block m_(1) . Initially spring is relaxed, both the blocks are at rest. What is acceleration of centre of mass of system at the instant of maximum elongation of spring

Two blocks of masses m_(1) and m_(2) are connected by an ideal sprit, of force constant k . The blocks are placed on smooth horizontal surface. A horizontal force F acts on the block m_(1) . Initially spring is relaxed, both the blocks are at rest. Which of the following statement is not true tn the watt of above system.

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

Consider a block connected to a light spring of spring constant 100Nm^(-1) . Now the block is displaced by applying a constant force F which gives zero resultant force when spring is stretched through 10 cm. Evaluate (i) Work done by the spring force when the block attains equilibrium. (ii) Net work done on the block when it attains maximum speed.

A block of mass m length force a verical of spring constant k If the block is polled down by a distance of 2mg//k from its equilibrium position and released for the subsequent in the spring to maximum compressed in it mg//k

A block of mass m = 2 kg is connected to a a spring of force constant k = 50 N//m . Initially the block is at rest and tlhe spring has natural length. A constant force F = 60 N is applied horizontally towards, the maximum speed of the block (in m//s ) will be (negelect friction).

Two blocks A and B, each of mass m, are connected by a spring of force constant K. Initially, the spring is in its natural length. A horizontal constant force F starts acting on block A at time t=0 and at time t , the extension in the spring is seen to be l . What is the displacement of the block A in time t ?
