One end of a light spring of spring constnat k is fixed to a wall and the other end is tied to a block placed on a smooth horizontal surface. In a displacement, the work done by the spring is `(1)/(2)kx^(2)`. The possible cases are
a) the spring was initially compressed by a distance x and was finally in its natural length
b) it was initially streched by a distance x and finally was in its natural length
c) it was initially in its natural length and finally in a compressed position
d) it was initially in its natural length and finally in a stretched position.

A

The spring was initially stretched by a distance x and finally was in ti's natural length

B

The spring was initially in it's natural length and finally compressed by a distance x

C

The spring was initially compressed by a distance x and finally was in it's natural length

D

The spring was initially in it's natural length and finally stretched by a distance x

One end of spring of force constant k is fixed to a vertical wall and the other to a block of mass m resting on a smooth horizontal surface. There is another wall at a distance, x_(0) from the block . The spring is then compressed by 2x_(0) and released. The time taken by the block to strike the other wall is

One end of a massless spring of spring constant 100 N/m and natural length 0.5m is fixed and the other end is connected to a particle of mass 0.5 kg lying on a frictionless horizontal table. The spring remains horizontal. If the mass is made to rotate at an angular velocity of 2 rad/s, find the elongation of the spring.
