Question: A transverse sinusoidal wave is generated at one end of a long, horizontal string by a bar that moves up and down through a distance

A transverse sinusoidal wave is generated at one end of a long, horizontal string by a bar that moves up and down through a distance of 1.00 cm. The motion is continuous and is repeated regularly 120 times per second. The string has linear density 120g/m and is kept under a tension of 90.0 N. Find the maximum value of
(a) The transverse speed u and
(b) The transverse component of the tension τ.
(c) Show that the two maximum values calculated above occur at the same phase values for the wave. What is the transverse displacement y of the string at these phases?
(d) What is the maximum rate of energy transfer along the string?
(e) What is the transverse displacement y when this maximum transfer occurs?
(f) What is the minimum rate of energy transfer along the string?
(g) What is the transverse displacement y when this minimum transfer occurs?
