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
