SI ma 81 sin _ 21 (RR) I (RR) 41. Two discs, each having mass m, are attached rigidly to the ends of a vertical spring. One of the discs rests on horizontal surface and the other produces a compression Xo on the spring when it is in equilibrium. How much further must the spring be compressed so that when the force causing compression is removed, the extension of the spring will be able to lift the lower disc off the table?

Two plates of some mass are attached rigidly to the two ends of a spring as shown in figure. One of the two ends of a spring s shown in figure. One of the plates resets on a horizontal surface to the other rusults a compression y of the spring when it is in equilibrium state. The further minimum compression required, so that when the force causing compression is removed the lower plate is lifted off the surface, will be :

Does the P.E. of the spring decreases or increases when it si compressed or stretched ?

When a spring is compressed by 0.05 m a restoring force of 10 N is developed in it. Then the force constant of the spring is

A 16kg block moving on a frictionless horizontal surface with a velocity of 4m//s compresses an ideal spring and comes to rest. If the force constant of the spring be 100N//m , then how much is the spring commpressed ?

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

Two blocks of masses m_1 and m_2 are attached to the lower end of a light vertical spring of force constant k. The upper end of the spring is fixed. When the system is in equilibrium, the lower block (m_2) drops off. The other block (m_1) will
