    1. A given string length L, connected at one end while the other end is free. Assume that the string moves in one dimensional, ie, the amplitude can be described by a function of the shape of his y (x, t).
    What is the average kinetic energy (as a string), assuming it moves with the lowest frequency possible?
    Given that when the string is perfectly horizontal its tension = To and amplitude motion is A.

    T0 = 2.76 [gram*cm/sec2]
    L = 5.25 [cm]
    A = 5.86 [cm]

    2. <sin2(at)>=<cos2(at)>=1/2. (average)

    3. With boundary conditions find the frequency of the wave vector, and then calculate the kinetic energy
