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`.

As, block of mass 5 kg is attached to spring balance reading of spring balance will be

"A mass is attached to one end of a spring and by holding the other end in hand, the spring is whirled in a horizontal circle" What happens to the length of the spring ?

A spring of spring constant 200N//m has a block of mass 1kg hanging at its one end and other end of spring is attached to ceiling of an elevator. The elevator is rising upwards with an acceleration g//3 . What should be the angular frequency and elongation during the time when the elevator is accelerating?

A spring of spring constant 200 N//m has a block of mass 1 kg hanging at its one end and form the other and the spring is attached to a celling of an elevator. The elevator rises upwards with an acceleration of g//3 . When acceleration is suddenly ceased , then what should be the angular frequency and elongationduring the time when the elevator is accelerating?

A spring of unstretched length 40 cm and spring constant k is attached to a block of mass 1 kg to one of its end. The other end of the spring is fixed on the top of a frictionless inclined plane of inclination theta = 45^(@) as shown in the figure, so that the spring extends by 3 cm. When the mass is displaced slightly and released the time period of the resulting oscillation is T. Determine the value of 5T close to nearest integer.

Block is attached to system of springs. Calculate equivalent spring constant. .

A block of mass 'm' is attached to a spring in natural length of spring constant 'k' . The other end A of the spring is moved with a constat velocity v away from the block . Find the maximum extension in the spring.

A block of mass m is attached with a spring in vertical plane as shown in the figure. If initially spring is in its natural length and the block is released from rest, then maximum extension in the spring will be

An ideal spring with spring constant k is hung from the ceiling and a block of mass M is attached to its lower end. The mass is released when the spring is initially unstretched. Then the maximum extension in the spring is
