A transverse sinusoidal wave is generated at one end of a long horizontal string by a bar that moves with an amplitude of 1.12 cm . The motion of the bar is continuous and is repeated regularly 120 times per second. The string has linear density of 117g/m. The other end of the string is attached to a mass 4.68 kg. The string passes over a smooth pulley and the mass attached to the other end of the string hangs freely under gravity.
The maximum magnitude of the transverse speed is

A

10.884 m/s

B

8.44 m/s

C

844 m/s

D
