A transverse wave on a string is modeled with the wave function y(x, t) = (0.60 m)sin[(0.85 m-1)x + (1.70 s)t + 0.20]. (Indicate the direction with the signs of your answers.) (a) Find the wave velocity (in m/s). 2 m/s (b) Find the position (in cm) in the y-direction, the velocity (in cm/s) perpendicular to the motion of the wave, and the acceleration (in cm/s) perpendicular to the motion of the wave of a small segment of the string centered at x = 0.40 m at time t = 5.00 s. position velocity acceleration 225 x cm cm/s cm/s
