Question

A.

A uniform wire is made from material with an average mass density of ρ=3,044kg/m3, a radius of 1.26 mm, and a length of 0.63m. The wire is held under a tension of 11.2 N. Transverse waves are sent down the wire.

What is the speed of the waves through the wire in m/s? Assume 3 significant figures

B.

A mass on a spring is undergoing simple harmonic motion in the x-direction with an amplitude of 0.86 m and a frequency of 11.4 Hz and a phase angle of 3.85 radians. What is the velocity of the particle at t = 8.05s?

Assume 3 significant digits and units of m/s.

C.

A mass on a spring is undergoing simple harmonic motion in the x-direction with an amplitude of 0.18 m and a frequency of 17.6 Hz and a phase angle of 4.62 radians. What is the location of the particle at t = 5.57s?

Assume 3 significant digits and units of meters.
