A transverse wave on a string is described by the equation y(x, t) = (2.27 cm) sin[(109 rad/s)t + (13 rad/s)x].
(a) What is the maximum transverse speed of a point on the string?
m/s
(b) What is the maximum transverse acceleration of a point on the string?
m/s2
(c) How fast does the wave move along the string?
(d) Why is your answer to (c) different from the answer to (a)?
