2. In SHM, if the particle's velocity is zero, what can be inferred about its position relative to the equilibrium?

3. A spring of k = 300 N/m has a 1.5 kg mass. If E = 0.75 J, what is the amplitude?

8. Which of the following motions is periodic but does not exhibit oscillatory behavior about a fixed point?

9. A particle in SHM has x = 6sin(3t - π/4) (in m). What is its acceleration at t = 0 s? (Take cos 45° = √2/2)
