A rope is stretched to a distance of 15.0 m and a single pulse is generated at one end. The time required for the wave to reach the other end of the rope is 1.50 s. What is the velocity of the wave?

- a 10 m long wire of mass of 123g is stretched under a tension of 255N. a generated at one end and 20ms later a second pulse is generated at the opposite end where n = mass of the wire / length = 123 x 10^-3 / 10 = 1.23 kg / m v = √ (255/1.23) = 14.4 m / s
