A wave pulse travels down a slinky. The mass of the slinky is m = 0.88 kilogram and is initially stretched to a length L = 7.3 meter. The wave pulse has an amplitude of A = 0.24 meter and takes t = 0.49 second to travel down the stretched length of the slinky. The frequency of the wave pulse is f = 0.4 Hertz.
1) Find the speed of the wave pulse?
2) Determine the tension in the slinky?
3) Determine the average speed of a piece of the slinky as a complete wave pulse passes?
4) Determine the wavelength of the wave pulse?
5) Now the slinky is stretched to twice its length (but the total mass does not change). Obtain the new tension in the slinky? (Assume the slinky acts as a spring that obeys Hooke's Law)
6) Evaluate the new mass density of the slinky?
7) Evaluate the new time it takes for a wave pulse to travel down the slinky?
8) If the new wave pulse has the same frequency, determine the new wavelength?
