A standing wave on a string of length L = 2 m is given by: y(x,t) = 4 sin(2rtx)cos(120rtt), where x and y are in centimetres and t is in seconds. The transverse speed of an element on the rope located at x = 15 cm at t = 2.3 s is: %3D O v(x,t) = 480n cm/s %3D O v(x,t) = 60 m/s %3D O v(x,t) = 60 cm/s O v(x,t) = 0 cm/s A standing wave on a string of length L = 2 m is given by: y(x,t) = 4 sin(2rtx)cos(120rtt), where x and y are in centimetres and t is in seconds.
