Problem 9: A mass M = I .3 kg is hanging from along string of length L = 19.9 m and total mass m = 19 kg. A student gives the mass 3 quick horizontal shake to set up a wave which travels upwards along the string. Part (a) What is the speed of the wave at the bottom of the string. in meters per second? Numeric : A numeric value is expected and not an expression. vb: Part (b) Express the tension of the chain at a height y above the bottom in terms of M, m, and 3. Expression : T0) = Select from the variables below to write your expression. Note that all variables may not be required. a.
