A rope of length L = 5.2 m with a total mass of m = 0.205 kg is tied to a hook rigidly mounted into a wall. A pulse of height 1.5 cm is sent down the rope. The tension in the rope is F = 34 N.
(A) Find the time between sending the pulse down the rope and detecting the pulse that returns.
(B) What is the height of the pulse that returns in cm?
