A certain traveling wave on a string obeys the function: y1(x, t) = 0.5m cos((0.25π rad/m) x + (1.25π rad/s) t) What is the direction and speed of this wave? negative in the x direction and 5m/s 2b. A second wave is traveling on the same string in the opposite direction and is described by the function, y2(x,t) = 1.2m cos((5.75 rad/m) x - (2.50 rad/s)t). What is the direction and speed of this wave? positive in the x direction and 0.43m/s 2c. The two waves overlap at the point x = 0.47 m when t = 3.2 s, what is the amplitude of the string at this point and time? y1(x, t) = 0.5m cos((0.25π rad/m) (0.47) + (1.25π rad/s)(3.2))=? i get 0.47m is this correct? y2(x,t) = 1.2m cos((5.75 rad/m) (0.47) - (2.50 rad/s)(3.2))=? 0.66m is this correct?

im looking for guidance on 2c
