A beetle whose mass is 2 g sits on a turntable at a distance of 12 cm from the center. The turntable is rotating at 33 rpm.

(a) What are its acceleration and the centripetal force on it?

a =______ m/s2

Fc=_____ N


(b) What is the interaction that provides the centripetal force? Select all that apply.

-the gravitational force
-the force of friction
-the force of the beetle on the turntable
-the concentration of the mind of the beetle

    At 33 rpm, the angular velocity is
    w = 33*2*pi/60 = 3.46 rad/s

    a = R*w^2, where R = 0.12 m
    a = 1.43 m/s^2
    Fc = M*a

    Friction of the bug on the turntable provides the centripetalo force
