obennoskey (blo242) – hw12 – Demkov – (59910) 2 x component of the particle’s acceleration at any time t a x = dv x dt = - ω 2 A cos( ω t + φ ) , so at t = 2 . 87 s , the x component of the particle’s acceleration is a x = - ω 2 R cos φ 2 = - (17 rad / s) 2 (6 . 4 m) cos(50 . 2276 rad) = - 1848 . 27 m / s 2 . 004 10.0 points When a body executes simple harmonic mo- tion, its period is 1. proportional to its acceleration. 2. independent of its amplitude. correct 3. the reciprocal of its speed. 4. inversely proportional to its accelera- tion. 5. proportional to its amplitude. Explanation: The period of simple harmonic motion is the same regardless of the amplitude.
