Answers to Problem Set 9

• Ch. 16

Answers for the even numbered problems:

16-28. (a) f = 5.58 Hz; (b) m = 0.325 kg; (c) x_m = 0.400 m.

16-34. This is a proof, so the answer is given.

16-36. (a) x = 0.450 m + W sin theta / k = 0.525 m. (b) T = 2 pi (W/kg)^1/2 = 0.69 s.

16-54. I = T² kappa / (4 pi²) = 7.9 x 10^-2 kg m².
