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.

A disc of mass m is connected with an ideal spring of stiffness k . If it is released from rest, it rolls without sliding on an inclination plane. The maximum elongation of the spring is:

A uniform circular disc of mass 'm' and radius 'R' is placed on a rough horizontal surface and connected to the two ideal non-deformed spring of stiffness k and 2k at the centre 'C' and point 'A' as shown . The centre of the disc is slighty displaced horizontally from equilibrium positon and then released, then the time period of small oscillation of the disc is (there is no slipping between the disc and the surface).

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

A disc of mass m and radius R is placed over a plank of same mass m. There is sufficient friction between disc and plank to prevent slipping. A force F is applied at the centre of the disc. Force of friction between the disc and the plank is
