A block of mass M executes SHM with amplitude a and time period T. When it passes through the mean position, a lump of putty of mass m is dropped on it. Find the new amplitude and time period.

A light spring of force constant k is attached to a block of mass M placed on a horizontal firctionless surface from its one end and other end is fixed to a right support. The system is executing S.H.M. of amplitude A_(1) and time period T_(1) . At some instant, the block passed through the equilibrium position and a small object of mass m is placed on it. The new amplitude and time period of the system now becomes A_(2) and T_(2) respectively. The ratio T_(2)/T_(1) is

A body of mass 10g executes SHM with amplitude 2 xx 10^(-2) m and time period 2 s Calculate the energy of the particle.

A particle of mass m executes SHM with amplitude A and frequency n. The average energy in one time period is

An iron ring of mass m_1 oscillates in its an plane with time period of pi sec. Assume that the amplitude of oscillation is small. When it is passing through the mean position, a magnet of mass m is attached to the lowest point. If the amplitude of oscillation decreases by factor of 7, find m/(m_1) .

A mass M attached to a horizontal spring executes SHM with an amplitude A_(1) . When mass M passes through its mean position a smaller mass m is placed over it and both of them move togther with amplitude A_(2) . Ratio of ((A_(1))/(A_(2))) is:
