A heavy load is suspended on a light spring. The spring is slowly pulled down at the midpoint (a certain work A is done thereby) and then released. Determine the maximum kinetic energy `W_(k)` of the load in the subsequent motion.

Force constant of a weightless spring is 16 Nm^(-1) . A body if mass 1 kg suspended from it is pulled down through 5 cm from its mean position and then released. The maximum kinetic energy of the body will be

A spring block system is placed on a rough horizontal floor. Force constant of the spring is k. The block is pulled to right to give the spring an elongation equal to x_0 and then it is released. The block moves to left and stops at the position where the spring is relaxed. Calculate the maximum kinetic energy of the block during its motion.

Two blocks P and Q of masses 0.3 kg and 0.4 kg respectively are stuck to each other by some weak glue as shown in the figure. They hand together at the end of a spring with a spring constant "k = 200 N m"^(-1) . The block Q suddenly falls free due to failure of glue, then find the maximum kinetic energy of the block P during subsequent motion (in mJ).

On suspending a heavy block of 2 kg from a massless spring, an extension of 5 cm is produced in the spring. If the block is further pulled down by 10 cm and then released then find the kinetic energy of oscillation of the spring.

Force constant of a weightless spring is 16 N/m. A body of mass 1.0 kg suspended from it is pulled down through 5 cm from its mean position and the released. The maximum kinetic energy of the system (spring+body) will be (0.0x) J. Find value of x.

A block of mass M is placed on a horizontal smooth table. It is attached to an ideal spring of force constant k as shown. The free end of the spring is pulled at a constant speed u. Find the maximum extension ( x_0 ) in the spring during the subsequent motion.

A spring has a natural length of 50 cm and a force constant of 2.0 xx 10^(3) N m^(-1) . A body of mass 10 kg is suspended from it and the spring is stretched. If the body is pulled down to a length of 58 cm and released, it executes simple harmonic motion. The net force on the body when it is at its lowermost position of its oscillation is (10x) newton. Find value of x. (Take g=10m/ s^(2) )

A block A of mass 2 kg is moving to right with a speed of 5 m/s on a horizontal smooth surface. Another block B of mass 2 kg, with a mass less spring of force constant K =200 N/m attached to it, is moving to left on the same surface with a speed of 3 m/s. Block A collides with the spring attached to B. Calculate (a) the final velocity of the block A. (b) the minimum kinetic energy of the system of two blocks during subsequent motion. (c) Repeat part (b) if there is no spring and the two blocks collide head on. Assume that the blocks are made of perfectly elastic material

A block attached with an ideal spring is kept on a smooth horizontal surface. Now the free end of the spring is pulled with a constant velocity u horizontally. Then the maximum energy stored in the spring and bock system during subsequent motion is :

A body of mass m is attached by an inelastic string to a suspended spring of spring constant k . Both the string and the spring have negligible mass and the string is inextensible and of length L . Initially, the mass m is at rest. Q. If the mass m is now raised up to point A (the top end of the string see fig. and allowed to fall from rest, the maximum extension of the spring in the subsequent motion will be
