The equation of motion of system is given by $m\ddot{x}+c\dot{x}+kx=0$. The damped vibration, ${\omega }_d$ can be written as:

A block of mass m = 5 kg is on the smooth inclined face of the wedge of mass M  = 10 kg , the inclination to the horizontal being θ = 37°.The wedge is resting on a smooth horizontal plane. Assuming the pulley P to be smooth and the string is light and inextensible. Find the acceleration of M, when M and m are always in contact.

[Given that $Sin {37}^o=\frac{3}{5}$ ]
