Exercise 6
One end of a long taut string is moved up and down in SHM with an amplitude of 0.15 m and a
frequency of 10 Hz. At time t = 0 the end of the string (at x = 0) has its maximum upward
displacement. The resultant wave travels down the string in the positive x-direction with a velocity of
50 m s -1. Obtain an equation describing the wave. A wire hangs vertically from a ceiling with a mass
of 10 kg attached to its lower end. The wire is 0.50 m long and weighs 25 g. (a) Calculate the wave
• velocity along the wire and the wavelength and frequency of the fundamental mode of vibration. (b) If
the maximum transverse displacement of the wire in the fundamental mode of vibration is 3.0 cm,
calculate the largest values of velocity and acceleration that a particle of the wire can have.
