Expert Solution
Step 1

(a) The equation for the position of the mass on the spring is given by:

x = 0.108 sin(9.24t + 0.82) + 0.683

Comparing this to the standard equation for simple harmonic motion:

x = A sin(ωt + φ)

where A is the amplitude, ω is the angular frequency, and φ is the phase angle, we can see that:

A = 0.108 m ω = 9.24 rad/s

The spring constant, k, is related to the angular frequency by the equation:

ω = sqrt(k/m)

where m is the mass of the object on the spring. Rearranging this equation gives:

k = mω^2

Substituting in the values for m and ω gives:

k = (0.407 kg)(9.24 rad/s)^2 ≈ 14.9 N/m

Therefore, the spring constant of the spring is approximately 14.9 N/m.
