Problem 7: Two students stretch a uniform rope of length L = 4.4 m and mass m = 1.1 kg between them. One of the students gives the rope a quick up-and-down shake and produces a transverse pulse that travels the length of the rope in time t = 1.3 s. Part (a) What is the tension in the rope, in newtons?

Problem 7: Two students stretch a uniform rope of length L = 4.4 m and mass m = 1.1 kg between them. One of the students gives the rope a quick up-and-down shake and produces a transverse pulse that travels the length of the rope in time t = 1.3 s. h L Part (a) What is the tension in the rope, in newtons? Numeric : A numeric value is expected and not an expression. T = Part (b) A third student uses a slow-motion camera to observe the pulse and measures that it takes a time t, = 0.15 s for the full width of the pulse to pass by her. She also carefully measures the height of pulse (from the equilibrium level of the rope to the pulse's peak) to be h = 0.15 m. What is the pulse's width, in meters? Numeric : A numeric value is expected and not an expression. w = 51 Part (c) A point on the rope is marked with a red spot. As the pulse passes by, what is the spot's average speed, in meters per second, during its transverse motion from equilibrium position to peak and back? Numeric : A numeric value is expected and not an expression. y = 2
