A particle moves in simple harmonic motion according to x = 2cos(50t), where x is in meters and t is in seconds. Its maximum velocity in m/s is:
A) 100 sin(50t)
B) 100 cos(50t)
C) 100
D) 200
E) none of these

Question

Quizplus · Accepted Answer

The maximum velocity in simple harmonic motion is given by the product of the angular frequency and the amplitude. Here, the amplitude is 2 meters and the angular frequency is 50 rad/s, so the maximum velocity is 50 * 2 = 100 m/s.
