Consider the sinusoidal wave of the figure below with the wave function y = 0.150 cos(15.7x- 50.3t) where x and y are in meters and t is in seconds. At a certain instant, let point A be at the origin and point B be the closest point to A along the x axis where the wave is 58.0° out of phase with A. What is the coordinate of B? ± cm y (cm) 40.0 cm 15.0 cm Aliy x (cm) Ⓡ
