The end of a stopped pipe is to be cut off so that the pipe will be open. if the stopped pipe has a total length l, what fraction of l should be cut off so that the fundamental mode of the resulting open pipe has the same frequency as the fifth harmonic (n=5) of the original stopped pipe?
express your answer in terms of l.

Asmall blob of putty of mass m falls from the ceiling and lands on the outer rim of a turntable of radius r and moment of inertia i0 that is rotating freely with angular speed ω0 about its vertical fixed-symmetry axis. (use any variable or symbol stated above as necessary.)
