Question

calculate the angular velocity of a body moving on a circular path with making an angle of 90 degree at the centre in 1 minute​

Answer 1

Answer: π/120

Explanation:

Let dw be the angular velocity here. So then,

dw = dθ/dt

where dθ is the angular displacement and dt is the time taken.

Here,

dθ = 90° = π/2 rad

dt = 1 min = 60 sec

Then,

dw = (π/2)/60 rad/sec

=π/120 rad/sec
