Question:

It is stated in Problem 59 that a pulse travels from the bottom to the top of a hanging rope of length L in a time interval Δt = 2√L/g. Use this result to answer the following questions. (It is not necessary to set up any new integration.)
(a) How long does it take for a pulse to travel halfway up the rope? Give your answer as a fraction of the quantity 2√L/g.
(b) A pulse starts traveling up the rope. How far has it traveled after a time interval √L/g?
