A spring with one end attached to a mass and the other to a rigid support is stretched and released.

A uniform light spring has unstretched length of 3.0 m. One of its end is fixed to a wall. A particle of mass m = 20 g is glued to the spring at a point 1.0 m away from its fixed end. The free end of the spring is pulled away from the wall at a constant speed of 5 cm/s. Assume that the spring remains horizontal (i.e., neglect gravity). Force constant of spring = 0.6 N / cm. (a) With what speed does the particle of mass m move? (b) Find the force applied by the external agent pulling the spring at time 2.0 s after he started pulling.

A mass m is attached to the free end of a massless spring of spring constant k with its other end fixed to a rigid support as shown in figure. Find out the time period of the mass, if it is displaced slightly by an amount x downward.

A chain of length 'L' and mass 'M' is hanging by fixing its upper end to a rigid support. The tension in the chain at a distance 'x' from the rigid support is
