Question: A transverse sinusoidal wave is moving along a string in the positive direction of an x axis with a speed of 80 m/s. At t

A transverse sinusoidal wave is moving along a string in the positive direction of an x axis with a speed of 80 m/s. At t = 0, the string particle at x = 0 has a transverse displacement of 4.0 cm from its equilibrium position and is not moving. The maximum transverse speed of the string particle at x = 0 is 16 m/s.
(a) What is the frequency of the wave?
(b) What is the wavelength of the wave? If the wave equation is of the form y(x, t) = ym sin (kx + wt + Φ), what are
(c) ym,
(d) k,
(e) w,
(f) Φ, and
(g) The correct choice of sign in front of w?
