Problem 8: A mass M = 2.3 kg is hanging from a long string of length L = 16.2 m and total mass m = 15 kg. A student gives the mass a 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. Vh = Part (b) Express the tension of the chain at a height y above the bottom in terms of M, m, and g. Expression: T(y) = Select from the variables below to write your expression. Note that all variables may not be required. a, B, 0, a, d, g, h, j, k, L, m, M, P, t, y Part (c) What is the speed of the wave, in meters per second, at the top of the string? Numeric : Anumeric value is expected and not an expression. Vt = Part (d) How long does it take, in seconds, for the wave to travel up the string? Numeric : Anumeric value is expected and not an expression. t =
