Answer:
a) λ = 1.12 m
b) f = 5.41 Hz
c) v = 154.54 m/s
d) A = 0.22m
e)
Explanation:
You have the following equation for a wave traveling on a cord:
(1)
The general expression for a wave is given by:
(2)
By comparing the equation (1) and (2) you have:
A: amplitude of the wave = 0.22m
k: wave number = 5.6 m^-1
w: angular velocity = 34 rad/s
a) The wavelength is given by substitution in the following expression:
b) The frequency is:
c) The velocity of the wave is:
d) The amplitude is 0.22m
e) To calculate the maximum and minimum speed of the particles you obtain the derivative of the equation of the wave, in time:
cos function has a minimum value -1 and maximum +1. Then, you obtain for maximum and minimum velocity:
