Two waves are traveling in opposite directions on the same string. The displacements caused by the individual waves are given by y1 = (21.8 mm)sin(9.00?t - 1.25?x) and y2 = (38.4 mm)sin(2.88?t + 0.400?x). Note that the phase angles (9.00?t - 1.25?x) and (2.88?t + 0.400?x) are in radians, t is in seconds, and x is in meters. At t = 3.76 s, determine the net displacement (in mm) of the string for the following values of x. Be sure to include the algebraic sign (+ or -) with your answers.
(a) x = 2.00 m
1Your answer is incorrect. mm
(b) x = 2.64 m
2Your answer is incorrect. mm
