(b) Using Eq. 15-12, we obtain ()()2220.12kg 10 rad/s1.2 10 N/m.kkmmωωπ=¡===×4. (a) The acceleration amplitude is related to the maximum force by Newton’s second law: Fmax= mam. The textbook notes (in the discussion immediately after Eq. 15-7) that the acceleration amplitude is am= ω2xm, where is the angular frequency (= 2π
