Two waves are traveling on a string. The displacement of the string due to each wave can be parametriza yi (x, t) = ymaxe (ax-bt)210 y2 (x, t) = ymore (cx+dt-$)-10 The constants are: a = 18.1 b = 30.4m c = 16.3 d = 27.4m o = 25.88m2 p = 11.92m ymax = 18.1mm At what time t do the two waves overlap so that the maximum displacement of the string is 2ymax
