Tension is maintained in a string as in the figure below. Theobserved wave speed is v = 22.0 m/swhen the suspended mass is m = 3.00 kg. (You mayassume that the length of the vertical portion of the string isnegligible compared to the length of the string.)
A string hangs over a pulley attached to the right end of atable. The left end of the string is attached to a wall, and thestring to the left of the pulley is horizontal. The string goesover the pulley and hangs vertically down, and at its bottom end isa suspended mass m.
(a) What is the mass per unit length of the string? kg/m(b) What is the wave speed when the suspended massis m = 2.10 kg? m/s
