A fellow student of mathematical bent tells you that the wave function of a traveling wave on a thin rope isy(x,t)= 2.10mm cos[( 6.96rad/m )x+( 744rad/s )t]. Being more practical-minded, you measure the rope to have a length of 1.34m and a mass of 3.38g .
Part A Determine the tension in the rope.
Part B Determine the average power transmitted by the wave.
