A body of mass 5.0 kg moves in simple harmonic motion according to the equation
X = 0.040 sin(30t + $\pi$/6)
Where the units are SI. The maximum speed of this body is approximately
A) 0.013 m/s
B) 0.40 m/s
C) 0.60 m/s
D) 1.2 m/s
E) 30 m/s

Question

Quizplus · Accepted Answer

The maximum speed in simple harmonic motion is given by the formula vmax = Aω, where A is the amplitude and ω is the angular frequency. Here, A = 0.040 m and ω = 30 rad/s. Thus, vmax = 0.040 * 30 = 1.2 m/s.
