In the figure shown the spring constant is K the mass of the upper disc is m and that of the lower disc is 3m the upper block is depressed down from its equilibrium position by a distance `delta=5mg//k` and released at t=0 find the velocity of m when normal reaction on 3m is mg

Find the time period of mass M when displaced from its equilibrium position and then released for the system shown in figure.

Two identical springs of spring constant k are attached to a block of mass m and to fixed supports as shown in figure. When the mass is displaced from equilibrium position by a distance x towards right, find the restoring force.

Tow identical springs of spring constant k are attached to a block of mass m and to fixed supports as shown in figure. When the mass is displaced from equilibrum position by a distance x towards right, find the restoring force.

Figure shows a system consisting of a massless pulley, a spring of force constant k and a block of mass m. If the block is slightly displaced vertically down from is equilibrium position and then released, the period of its vertical oscillation is

A block whose mass m is 680g is fastened to a spring whose spring constant k is 65N/m. The block is pulled a distance x=11cm from its equilibrium position at x=0 on a frictionless surface and released from rest at t= 0. What is the amplitude of the oscillation?

A block whose mass m is 680g is fastened to a spring whose spring constant k is 65N/m. The block is pulled a distance x=11cm from its equilibrium position at x=0 on a frictionless surface and released from rest at t= 0. What is the phase constant phi for the motion?

Two identical metal plates with area A and mass m are kept separated by help of three insulating springs as shown in the Figure. The equilibrium separation between the plates is d_(0) (gt gt sqrt(A)) and force constant of each spring is K. When a constant voltage source having emf V is connected to the plates, the equilibrium separation changes to d. Assume that the lower plate is fixed and the upper plate is free to move. (a) Find V in terms of given parameters. (b) If the upper disc is slightly displaced from its equilibrium position and released, calculate the time period of its oscillation.

Figure shows two discs of same mass m. They are rigidy attached to a spring of stiffness k. The system is in equlibrium. From this equilibrium position, the upper disc is pressed down slowly by a distance x and released. Find the minimum vlue of x, if the lower disc is just lifted off the ground.
