Two equal masses are attached to the two end of a spring of force constant k the masses are pulled out symmetrically to stretch the spring by a length 2x_(0) over its natural length. Find the work done by the spring on each mass.

When a 20 g mass hangs attached to one end of a light spring of length 10 cm, the spring stretches by 2 cm. The mass is pulled down until the total length of the spring is 14 cm. The elastic energy, (in Joule) stored in the spring is :

a block of mass 0.1 kg attached to a spring of spring constant 400 N/m pulled horizontally from x=0 to x_1 =10 mm. Find the work done by the spring force

A block Q of mass 2m is placed on a horizontal frictionless plane. A second block of mass m is placed on it and is connected to a spring of spring constant K, the two block are pulled by distance A. Block Q oscillates without slipping. The work done by the friction force on block Q when the spring regains its natural length is:

Block A of mass m is placed on a plank B . A light support S is fixed on plank B and is attached with the block A with a spring of spring constant K . Consider that initially spring is in its natural length. If the plank B is given an acceleration a, then maximum compression in the spring is (xma)/(k) . Find the value of x (All the surface are smooth)

A spring of force constant K is first stretched by distance a from its natural length and then further by distance b. The work done in stretching the part b is

A ball of mass m is attached to the lower end of a light vertical spring of force constant K . The upper end of the spring is fixed. The ball is released from rest with the spring at its normal ( unstretched ) length, and comed to rest again after descending through a distance x .

An elevatore is moving up with a constant velocity. Two different masses are attached to two different springs of same spring constant. Say you do two operations expanding the spring or compressing the spring by the same distance. Which operation consumes more energy: expanding the spring or compressing it?

Two masses m and 2m are attached to two ends of an ideal spring as shown in figure. When the spring is in the compressed state, the energy of the spring is 60 J, if the spring is released, then at its natural length

A spring is stretched by distance x and then compressed to same distance from its original length. The work done by the spring force is (k=spring constant)
