Quiz 2 A fellow student with a mathematical bent tells you that the wave function of a traveling wave on a thin rope is y(x,t)= 2.3 mm cos[(6.98 rad/m) x + (742 rad/s) t]. Being more practical you measure the rope to have a length of 1.35 m and a mass of 0.00338 kg. You are asked to determine the following: a) Amplitude
