If one end of vertical spring is connected to ground and other end is connected to horizontal platform at rest. If a ball of mass m is dropped on it from height h above platform compresses spring by h/2. If h= 10cm then find k

A block of mass m is dropped from height h above the ground. Find out the speed of the block when it reaches the ground.

A block is released from height h , find the maximum compression of spring of spring constant k .

Given figure shows a massless platform kept on a light elastic spring attached to ground from one end . A small particle of mass 0.2 kg is dropped on the paltform from a height of 0.26 m , which causes a compression of 0.01 m in the spring . Calculate the height from which the particle must be dropped in order to cause a compressin of 0.05 m .

Figure. shows a rough horizontal plane which ends in a vertical wall, to which a spring is connected, having a force constant k. Initially spring is in its relaxed state. A block of mass m starts with an initial velocity u towards the spring from a distance l_(0) from the end of spring shown. When block strikes at the end ofthe spring, it compresses the spring and comes to rest. Find the maximum compression in the spring. The friction coefficient between the block and the floor is mu ..

In Fig. three identical massless springs are kept horizontal. The left end of the first is tied to a wall. The left end of the second spring is tied to a block of mass m placed on rough ground and the ,eft end of the third spring is tied to a block of mass m placed frictionless ground. The right end of each spring is pulled by a force that is increased gradually from zero to F. Extensions in these springs are x_(1) , x_(2) and x_(3) , respectively. Find the relationship between x_(1) , x_(2) , and x_(3)

A block of mass m initially at rest is dropped from a height h on to a spring of force constant k . the maximum compression in the spring is x then

A small mass 'm' is sliding down on a smooth curved incline form a height 'h' and finally moves through a horizontal smooth surface. A light spring of force constant K is fixed with a vertical rigid stand on the horizontal surface, as shown in the figure. Find the value for the maximum compression in the spring if mass 'm' is released from rest from height 'h' and hits the spring in the horizontal surface. .

The figure shows a smooth curved track terminating in a smooth horizontal part. A spring of spring constant 400(N)//(m) is attached at one end to a wedge fixed rigidly with the horizontal part . A 40 g mass is released from rest at a height of 5 m on the curved track. The maximum compression of the spring will be
