Question

A tightrope walker begins crossing a rope at t = 0 s and walks at a speed of 1.0 m/s as shown below. After 12.0 s, a large bird lands on the far end of the rope and the acrobat stops walking. The bird causes a transverse wave pulse to move along the rope, toward the acrobat. If the rope has a tension of 3.00 kN, a mass of 10.0 kg and is 30.0 m long, how long after the bird lands does the pulse reach the tightrope walker? [ans. 0.19 s]
