Question

need help (waves and sound)

Answer 1

A wave pulse travels down a slinky. The mass of the slinky is
\(\rm m = 0.91~kg\) and is initially stretched to a length \(\rm L = 6.3~m\).
The wave pulse has an amplitude of \(\rm A = 0.23~m\) and takes
\(\rm t = 0.45~s\) to travel down the stretched length of the slinky.
The frequency of the wave pulse is \(f \rm = 0.42~Hz\).

Answer 2

What is the speed of the wave pulse?

Answer 3

Got it figured... nvm
