Question

A 1 kg mass and a 6 kg mass are attached to either end of a 3 mlong massless rod.

a.) Find the center of mass of the system.
___m, from the 1 kg mass.

Find the rotational inertia (I) of the system when rotatedabout:
b.) the end with the 1 kg mass.
___kg m2
c.) the end with the 6 kg mass.
___kg m2
d.) the center of the rod.
___kg m2
e.) the center of mass of the system.
___kg m2
(Compare this to parts b-d. Is this what you expect?)

f.) If the system is rotated about the center of mass by a force of10 N acting on the 6 kg mass, (perpendicular to the rod), what willthe size of the angular acceleration of the system be?
___rad/s2
