An ideal spring supports a disc of mass M. A body of mass m is released from a certain height from where it falls to hit M. The two masses stick together at the moment they touch and move together from then on . The oscillations reach to a height a above the original level of the disc and depth b blow. it The constant of the force of the spring is

A mass M is in static equilibrium on a massless vertical spring as shown in the figure. A ball of mass m dropped from certain height sticks to the mass M after colliding with it. The oscillations they perform reach to height'a' above the original level of scales & depth 'b' below it. (a) Find the constant of force of the spring., (b) Find the oscillation frequency. (c ) What is the height above the initial level from which the mass m was dropped?

A body of mass m is released from a height h to a scale pan hung from a spring. The spring constant of the spring is k , the mass of the scale pan is negligible and the body does not bounce relative to the pan, then the amplitude of vibration is

A block of mass m is released from a height h from the top of a smooth surface. There is an ideal spring of spring constant k at the bottom of the track. Find the maximum compression in the spring (Wedge is fixed)

A body A of mass 4 kg is dropped from a height of 100 m. Another body B of mass 2 kg is dropped from a height of 50 m at the same time. Then :

A body of mass m when released from rest from a height h, hits the ground with speed sqrt(gh) . Find work done by air resistance force.
