Given the equation x(t) = A cos(ωt + φ) for a mass oscillating on a spring, what is the frequency of this motion?

(II) Figure 14–29 shows two examples of SHM, labeled A and B. For each write the equations for both A and B in the form of a sine or cosine.

A 15-cm-long tendon was found to stretch 3.7 mm by a force of 13.4 N. The tendon was approximately round with an average diameter of 8.5 mm. Calculate Young’s modulus of this tendon.

A mass-spring system with an angular frequency ω = 8π rad/s oscillates back and forth. (a) Assuming it starts from rest, how much time passes before the mass has a speed of 0 again? (b) How many full cycles does the system complete in 60s?
