A block of mass `0.9 kg` attached to a spring of force constant `k` is lying on a frictionless floor. The spring is compressed to `sqrt(2) cm` and the block is at a distance `1//sqrt(2) cm` from the wall as shown in the figure. When the block is released, it makes elastic collision with the wall and its period of motion is `0.2 sec`. Find the approximate value of `k`

A block of mass 100 g attached to a spring ofstiffness 100 N//Mis lying on a frictionless floor as shown. The block is moved to compress the spring by 10 cm and released. If the collation with the wall is elastic then find the time period of oscillations.

A block of mass 100 g attached to a spring of stiffness 100 N//m is lying on a frictionless floor as shown. The block is moved to compress the spring by 10 cm and released. If the collision with the wall is elastic then find the time period of oscillations.

In the figure, the block of mass m, attached to the spring of stiffness k is in correct with the completely elastic wall, and the compression in the spring is e. The spring is compressed further by e by displacing the block towards left and is then released. If the collision between the block and the wall is completely eleastic then the time period of oscillation of the block will be
