Awave pulse travels down a slinky. the mass of the slinky is m = 0.87 kg and is initially stretched to a length l = 6.8 m. the wave pulse has an amplitude of a = 0.23 m and takes t = 0.478 s to travel down the stretched length of the slinky. the frequency of the wave pulse is f = 0.48 hz.
1) what is the speed of the wave pulse? m/s2) what is the tension in the slinky? n3) what is the wavelength of the wave pulse? , clearly work it out correctly..thnks
