An object moves in a circular path of radius 0.5m with a speed of 1m/?. What is its angular velocity?

A. 8???/?

B. 4???/?

C. 1???/s

D. 2???/s

QUICK ANSWER…

D

EXPLANATION…

V = Rw

Where V = linear speed = 1m/s

R = radius = 0.5m,

w = angular velocity = ?

so, w = V/R = 1/0.5 = 2rad/s

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is incorrect.
  3. C is incorrect.
  4. D is the correct answer.

HELPFUL TIPS…

You may please note these/this:

  • Linear speed of circular motion = radius of rotation x angular velocity.
