Question

The figure below shows a segment of a wave traveling on a tensioned wire in the positive x-direction. The wave speed is 60 m/s. Find the velocity at positions a, b, and c at the instant the segment was captured.

Graph showing wave function with points a, b, c and wave speed of 60 m/s.

Accepted Answer

v_a = - 38 m/s
v_b = 0 m/s
v_c = 38 m/s

Answer

v_a = 38 m/s
v_b = 0 m/s
v_c = 38 m/s

Answer

v_a = 38 m/s
v_b = 0 m/s
v_c = - 38 m/s

Answer

v_a = - 470 m/s
v_b = 0 m/s
v_c = 470 m/s
