The transverse displacement of a harmonic wave on a stretched rope is y = 0.04 cos(2.8 t - 2.2 x), where x and y are in meters and t is in seconds. A 5 meter length of this rope has a mass of 1.5 kg.

a) At time t = 0, consider a 1/2 wavelength long section of the rope which is carrying the wave between two points which have zero displacement (y = 0). What is the total force exerted by the rest of the rope on this section? (You may neglect any effects due to the weight of the rope.)
