A block hangs in equilibrium from a vertical spring. When a second identical block is added, the original block sags by 5.00 cm. What is the oscillation frequency of the two block system?

  • Physics -

    F=kx = mg

    but for the second block we have


    setting the x equal..

    k= mg/.05

    now frequency:

    f= 1/2pi sqrt (k/m)

    put that k int the expression, and you have the answer.
