I need help with this problem, please and thank you!

A cable of length ?and density ρ[mass/length] is stretched under a tension τ. One end of the cable is connected to a mass ?, which can move in a friction-less slot, and the other end is fastened to two springs of stiffness ?/2, as shown in the figure. Write down its governing equation,boundary conditions and then calculate its natural frequency.

    Please be clear in what equations were used thank you! A heavy stone of mass m is hung from the ceiling by a thin 8.25-g wire that is 65.0 cm long. When you gently pluck the upper end of the wire, a pulse travels down the wire and returns 7.84 ms later, having reflected off the lower end. The speed of sound in the room is 344 m/s, and the stone is heavy enough to prevent the lower end of...
