The Vertical Displacement Y(x,t) of a Horizontal String Aligned Along

question 14

Short Answer

The vertical displacement y(x,t) of a horizontal string aligned along the x-axis is given by the equation y(x,t) = (6.00 mm) cos[(3.25 m^-1)x - (7.22 s^-1)t]. What are the (a) speed and (b) amplitude of this wave?
