The total length of the cord is l = 7.00 m, the mass of the cord is m = 7.00 g, the mass of the hanging object is m = 2.50 kg, and the pulley is a fixed a distance d = 4.00 m from the wall. you pluck the cord between the wall and the pulley and it starts to vibrate. what is the fundamental frequency (in hz) of its vibration?
