A steel cable with a total length of 27.7 m and total mass of 91 kg is connected to two poles. The tension in the cable is 869 N and the wind makes the cable vibrate at a frequency of 4.6 Hz. Calculate the wavelength of the resulting wave on the cable. Hint: This is a two part problem where you have to use the length, mass and tension to calculate the velocity of a wave on the cable and then use the velocity to solve the last part of the problem.
A force vector has a magnitude of 590 newtons and points at an angle 44o of below the positive x axis. What is (a) x scalar component and (b) y scalar component of the vector.
