For the rotational part of the experiment, a student measures a force of 1.8 n when the radius is 12 cm and the angular velocity 10 rad/s.

a. what is the total mass of the object undergoing uniform circular motion?

b. if the same mass (at the same radius) is rotated at 5 rad/s, what will be the measured force?

Ans : The total measured force will be : total centripetal force F = m*r*w^2 F = force r = radius w = angular velocity 1.8 = m*0.12*10^2 mass m = 0.15 kg
