An object moves in a circular path of radius 0.5m with a speed of 1m/?. What is its angular velocity?
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:
- Option A is incorrect.
- Option B is incorrect.
- C is incorrect.
- D is the correct answer.
You may please note these/this:
- Linear speed of circular motion = radius of rotation x angular velocity.
