A block of mass `m` connected to a spring of stiffness `k` is placed on horizontal smooth surface. When block is at `x=0`, spring is in natural length. The block is also subjected to a force `F=(k|x|)/(@)` then

A block of mass m is attached to a spring of force constant k whose other end is fixed to a horizontal surface. Initially the spring is in its natural length and the block is released from rest. The average force acting on the surface by the spring till the instant when the block has zero acceleration for the first time is

The two blocks A and B of same mass connected to a spring and placed on a smooth surface. They are given velocities (as shown in the figure) when the spring is in its natural length :

A block of mass M is tied to a spring of force constant k and placed on a smooth horizontal surface. The natural length of the spring is L. P is a point on the spring at a distance (L)/(4) from its fixed end. The block is set in oscillations with amplitude A. Find the maximum speed of point P on the spring.

A block of mass m is connected to a spring of force constant k. Initially the block is at rest and the spring has natural length. A constant force F is applied hrizontally towards right. The maximum speed of the block will be (there is no friction between block and the surface)

A block of mass m, attacted to a string of spring constant k, oscillates on a smooth horizontal table. The other end of the spring is fixed to a wall. The block has a speed v when the spring is at its natural length. Before coming to an instantaneous rest. If the block moves a distance x from the mean position, then

Two blocks A and B of masses m and 2m respectively are connected together by a light spring of stiffness k and then placed on a smooth horizontal surface. The blocks are pushed towards each other such that spring gets compressed by a length x_(0) and then released from rest. Find the work done on the block A by the spring, by the time the spring acquires its natural length.

A block of mass m = 2 kg is connected to a a spring of force constant k = 50 N//m . Initially the block is at rest and tlhe spring has natural length. A constant force F = 60 N is applied horizontally towards, the maximum speed of the block (in m//s ) will be (negelect friction).
