If an object which mass is 3kg moves in a circular path of a radius 0.7m; record a speed at 2m/s what is the result of the angular velocity?

A. 4 rads−¹
B. 1rads−¹
C. 3 rads−¹
D. 4rads−¹

Correct Answer:

Option C – 3 rads−¹

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−¹ Angular velocity (w) = 3rads−¹
