Consider transverse waves moving along a stretched spring Suppose the mass of the spring is 10 grams, its relaxed (not stretched) length is 1.00 meters, and its spring constant (if stretched) is 5.0 N/cm. The spring is tensioned via the pulley wheel and a hanging weight (as in the experiment). The final length of the stretched spring is 1.50 meters (from the oscillator to the weight). According to Eqn 2, how fast will transverse waves propagate along this stretched spring? SHOW YOUR WORK.
Homework Answers
Tension in the spring is F = k*x
F = 500 N/m*(1.5-1) = 500*0.5 = 250 N
linear density is mu= m/l = 0.010/1 = 0.01 kg/m
speed of the transverse wave is v =Sqrt(F/mu) = Sqrt(250/0.01) = 158.11 m/s

DQuestion 5 1 pts A simple harmonic oscillator at the point x-0 generates a wave on a horizontal rope. The oscillator operates at a frequency of 40.0 Hz and with an amplitude of 3.00 cm. The rope has a linear mass density of 50.0 g/m, and is stretched with a tension of 5.00 N. Find the maximum transverse acceleration of points on the rope, in m/s?
