###### PAGE 3 (25 pts): You have a string with a length of 2.9m and a mass of 12.5 grams_ You attach it to a vertical wall. After travelling horizontally for 2.1 meters, the string passes over a pulley: A mass M hangs down from the pulley, and the distance between the pulley and the mass is 0.8 meters When you pluck the string, it oscillates with a frequency of 224 Hz. It oscillates in the following pattern: There is a node at the wall, 2 nodes at intermediate positions along the string; and a node at

It oscillates in the following pattern: There is a node at the wall, 2 nodes at intermediate positions along the string; and a node at the pulley: There are a total of 3 antinodes along the horizontal length of the string: The vertical part of the string is not vibrating: What is the amount of mass M which is hung from the pulley? Give your final answer in grams. 2. Tos
