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)= 2.30mmcos[(6.98rad/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 then asked to determine the following:
A) Amplitude
B) Frequency
C) Wavelength
D) Wave Speed
E) Direction the wave is traveling
F) Tension in the rope
G) Average power transmitted by the wave
