Here Are the Equations for the Three Waves Traveling on Separate

Here are the equations for the three waves traveling on separate strings. Rank them according to the maxium transverse speed, least to greatest.
Wave 1: y(x,t) = (2.0 mm) sin [(4.0 m^-1) x - (3.0 s^-1) t]
Wave 2: y(x,t) = (1.0 mm) sin [(8.0 m^-1) x - (4.0 s^-1) t]
Wave 3: y(x,t) = (1.0 mm) sin [(4.0 m^-1) x - (8.0 s^-1) t]
