A string has a linear density of 5.60 10-3 kg/m and is under a tension of 245 N. The string is 1.9 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown below in the drawing. (a) Determine the speed of the traveling wave. m/s (b) Determine the wavelength of the traveling wave. m (c) Determine the frequency of the traveling waves that make up the standing wave.

A "seconds pendulum" is one that moves through its equilibrium position once each second. (The period of the pendulum is precisely 2.000 s.) The length of a seconds pendulum is 0.9928m at Tokyo and0.9941m at Cambridge, England.
A block of mass m = 2.0 kg attached to a spring with spring constant k on a frictionless surface. The block is pushed to the left to position x = -0.5 m and, at time t = 0, it is released from rest and starts oscillating with a period of 2.0 s.
