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 is C

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
