Homework Help: Physics

Posted by Kevin on Tuesday, November 15, 2011 at 4:07pm.

A high school cheerleader has a baton that is 1 meter long with a 100 gram mass on each end. Another cheerleader has a baton that is 0.5 meter long with the same mass on each end. Neglecting the mass of the rod holding the masses together, which baton will be easier to spin when grasped at the center?

A. The longer baton because it has more mechanical advantage due to a longer lever arm.
B. The shorter baton because it requires less force to move the mass at the end.
C. The shorter baton because it requires less torque.
D. Both batons will be just as easy to spin since the mass of the rod is negligible
