If an object whose mass is 3kg moves in a circular path of a radius 0.7m,…

If an object whose mass is 3kg moves in a circular path of a radius 0.7m, records a speed at 2m/s. What is the result of the angular velocity?

  • A.
    4 rads–1
  • B.
    1rads–1–1
  • C.
    3–1rads–1
  • D.
    4rads–1–1
Correct Answer: Option C
Explanation

M= 3kg, r = 0.7m, v = 2m/s
v = wr
w = angular velocity
r = radius in an tangential circular
v = speed of an object
W = V/δ = 2/ 0.7 = 2.85
W = 2.853rads–1 (total interest whole number)
W = &approx.; 3rads–1Angular velocity (w) = 3rads–1
