Two waves are traveling in opposite directions on the same string. The displacements caused by the individiual waves are given byy1=(30.0 mm)sin(9.39πt -1.66πx) and y2=(39.0mm)sin(3.54πt + 0.552πx). Note that thephase angles (9.39πt - 1.66πx) and(3.54πt + 0.552πx) are in radians,t is in seconds, and x is in meters. Att = 5.00 s, what is the net displacement (in mm) of thestring at (a) x = 2.22 m and(b) x = 2.57 m? Be sure to include thealgebraic sign (+ or -) with your answers.
