Figure shows transverse acceleration ay versus time t of the point on a string at x = 0, as a wave written in the form y(x, t) = ym sin (kx ?? wt + ?) passes through that point. The scale of the vertical axis is set by as = 400 m/s2. What is ?? (Caution: A calculator does not always give the proper inverse trig function, so check your answer by substituting it and an assumed value of co into y(x, t) and then plotting the function.)
