A sping of spring constant k is attached to the ceiling. A block of mass M is attached to its lower end and is released suddenly. (ii) Find its speed at the instant it passes throught the equilibrium position.

A block of mass m attached in the lower and vertical spring The spring is hung from a calling and force constant value k The mass is released from rfest with the spring velocity unstrached The maximum value praduced in the length of the spring will be

In the shown diagram mass of A is m and that of B is 2 m. All the surfaces are smooth. System is released from rest with spring unstretched. Then, the maximum extension (x_(m)) in spring will be:

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

spring of force constant k clamped rigidly at onoe end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in figure is stretched by the same force F. (a) What is the maximum extension of the spring in the two cases ? (b) If the mass in figure and the two masses in figure are released free, what is the period of oscillation in each case?

A spring has natural length 40 cm and spring constant 500 N//m . A block of mass 1 kg is attached at one end of the spring and other end of the spring is attached to a ceiling. The block is relesed from the position, where the spring has length 45 cm .
