An angular velocity of 60 revolutions per minute is the same as:
Correct answer: D. 2π rad/s
- A. 1/2π rad/s
- B. 120π rad/s
- C. 30/π rad/s
- D. 2π rad/s
Explanation
Angular velocity is denoted by ω.As given,ω = 60 rev/min1 rev = 2π rad, and 1 min = 60 s. Putting values,ω = 60 x 2π/60 rad/s= 2π rad/sHence, option D is the correct option.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
