The angular speed of an object describes a circle of radius 4m with  linear constant speed of 10m/s is

  1. A2.50 rads\(^{-1}\)
  2. B1.58 rads\(^{-1}\)
  3. C14.00 rads\(^{-1}\)
  4. D40.00 rads\(^{-1}\)

Explanation

The relationship between linear speed (v) and angular speed (ω) is v = ωr. Rearranging the formula gives ω = v / r = 10 / 4 = 2.50 rads⁻±.
