Please turn in this sheet stapled to the top of your work. Physics Problems: 1. One end of a 10 m long rubber tube is attached to a fixed support. A cord attached to the other end passes over a pulley and supports and object of mass 10 kg. The mass of the rubber tube is 0.5 kg. If the tube is struck with a traverse blow at one end, how long does it take for the resulting disturbance to reach the other end? 2. A transverse wave on an ideal string (no forces other than tension) is described by y ( x,t ) = Ae i ( kx ω t+ φ ) where A = 1 cm, ω = 2000 rad/s, k = 20 rad/m and φ = 53 ° . The mass per unit length is 0.05 kg/m. (a) Sketch a snapshot (a graph of y vs. x ) of the string at t = 0, with numerical values on the axes. Identify one point on your graph for each of the following conditions: (A)
