Homework Answers
Solution) Amplitude , A = 1.27 cm = 1.27×10^(-2) m
Frequency , f = 2.55 Hz
Maximum speed , V = ?
V = Aw
But w = 2(pi)f = 2(pi)×2.55 = 16.02 rad/s
V = Aw
V = 1.27×10^(-2)×16.02
V = 0.203 m/s

As you walk, the upper part of your body moves up and down with approximately simple harmonic motion. The smaller the amplitude of this motion the smaller the force you put on your joints and, of course, the more graceful is your walk. If you managed to
As you walk, the upper part of your body moves up and down with approximately simple harmonic motion. The smaller the amplitude of this motion the smaller the force you put on your joints and, of course, the more graceful is your walk. If you managed to develop your walk so that you have kept the amplitude down to 1.60 cm, what is the maximum acceleration of your body, in units of g = 9.80 m/s2, when you are walking at your...
