A wave has a known propagation velocity of 4.32 m/s and a wavelength of 0.388 meters. The amplitude of the wave is 38.2 cm. You may assume the wave height is zero at t=0 seconds and x=0 meters.
1. What is the position equation of the wave? should be in the format of x(t)=Acos(wt)
2. Draw a graph illustrating the position dependence of the wave. Be sure to label graph numerically.
