The following given is for questions 14 and 15: Consider a taut string of linear mass density u = 0.04 kg/m, stretched by a mass m as shown in the figure below. Vrate The propagating wave produced by a vibrator on one end of the string is represented by the wave function: y(x, e) = 0.05 sin(3rx - 18nt + g) where x and y are in meters and t is in seconds. 14) If at t = 0, an element at x = 0 has a vertical displacement y = -0.025 m and is moving upward, then the phase angle o is equal to: 15) Suppose that the speed of this wave is v. In order to double its speed, the mass m suspended from the string should be multiplied by a factor of:

The propagating wave produced by a vibrator on one end of the string is represented by the wave
function:
y(x, t) = 0.05 sin(37x - 18nt + 4)
where x and y are in meters and t is in seconds.
14) If at t = 0, an element at x = 0 has a vertical displacement y = -0.025 m and is moving upward,
then the phase angle p is equal to:
