Figure shown a block P of mass m resting on a smooth horizontal ground, attached to one and a spring of force constant k in netural length. If another block od same mass and moving with a velocity u towards right is placed on the block on which stick to it due to friction ,find the time it will take to reach its exterme position. Also find the amplitude of oscillation of the combined mass `2m`.

Consider a block of mass 'm' attached to a spring of spring constant 'K' as shown. Now a block of same mass 'm' moving with velocity 'u' strikes the other block and stick to it. Both blocks collectively start performing SHM . The amplitude (A) of their SHM is

Figure shown a block P of mass m resting on a smooth horizontal surface, attached to a spring of force constant k which is rigidly fixed on the wall on left side, shown in the figure . At a distance l to the right of the block there is a rigid wall. If block is pushed towards left so that spring is compressed by a distance 5l//3 and when released, if will starts its oscillations. If collision of block with the wall is considered to be perfectly elastic. Find the time period of oscillation of the block.
