Question
One end of a nylon rope is tied to a brick wall. The rope is stretched horizontally, passed over a pulley 80 meters away, and weighted with a mass 180.0 kg at the end. Waves on the rope are measured, and found to travel at 150 m/s. What is the mass of the rope between wall and pulley? If the rope is shaken sideways at 24.0 Hz, what is the wavelength of the waves produced?

Answer:
Mass of the rope m = 6.272 kg
Wavelength is equal to 6.25 m
Explanation:
Length of pulley L = 180 M
Mass at the end of pulley m = 180 kg
Frequency is given f = 24 Hz
Acceleration due to gravity
Tension
Velocity of wave in the rope v = 150 m/sec
Velocity of wave is given by
Therefore mass of the rope
Wavelength is equal to
