A particle moves in simple harmonic motion with an amplitude of 0.20 m and an angular frequency of 5.0 rad/s. What is the maximum speed of the particle?
Show the answer and explanation
Correct answer
B. 1.0 m/s
Principle or equation
In simple harmonic motion, the maximum speed is v_max = A ω, where A is amplitude and ω is angular frequency.
Why this answer is correct
Substitute A = 0.20 m and ω = 5.0 rad/s: v_max = 0.20 × 5.0 = 1.0 m/s.
Example
If amplitude is 0.10 m and angular frequency is 10 rad/s, v_max = 0.10 × 10 = 1.0 m/s.
