A tray of mass 12 kg is supported by two identical springs as shown in figure. When the tray is pressed down slightly and released, it executes SHM with a time period of 1.5s. What is the force constant of each spring?When a block of mass m is placed on the tray , the period of SHM changes to 3.0s. What is the mass of the block ?

A tray of mass 12 kg is supported by tow identical spring as shown in figure. When the tray is pressed down slightly and then relased , it executes SHM with a time peroid of 1.5 s.The spring constant of each spring is .

A tray of mass M=10kg is supported on two identical springs, each of spring constant k, as shown in figure, when the tray is depressed a little and released, it executes simple harmonic motion of period 1.5 s. when a block of mass m is placed on the tray, the speed of oscillation becomes 3 s. the value of m is

An arrangement of three identical spring and a block of mass 10 kg is shown in the adjoining figure. When the platform on which block is placed is slightly pressed down and released. It performs S.H.M. with a period of 2 s. (i) Calculate the spring constant of the spring. (ii) If a block of mass m is further placed on the platform, the new period of S.H.M. becomes 3.5 s. Find the value of m. (Assume platform to be massless)

A block of mass m is suspended by different springs of force constant shown in figure.

A block of mass m is connected to three springs as shown in Fig. The block is displaced down slightly and left free, it starts oscillating. Find time period of oscillations.

A block of M is suspended from a vertical spring of mass m as shown in the figure. When block is pulled down and released the mass oscillates with maximum velocity v .
