A barbell consists of a 0.50 kg ball and 2.00 kg ball connected at their centers by a masslessthreaded rod of length 0.50 m. To receive full credit, include with your correct solution an annotatedsketch of the situation.a. Where is the center of mass of the barbell?b. What is the linear speed of each ball if the barbell rotates about its center of mass at 40.0 rpm?
To make sure you know how to calculate the clockwise and counterclockwise torque using any point, do the same using the center of mass of the bar (the halfway point) as the axis for your torque calculations.
5. Calculate the magnitude of net clockwise torque.
6. Calculate the magnitude of the net counterclockwise torque.

The diagram below indicates four different combinations of (1) net force on the rod, Fnet, and (2) net torque on the rod about its center of mass, Tnet. In each box, draw vectors that represent one or two forces that achieve the given combination of net force and net torque. If any combination is not possible, state so explicitly. looge ad For example: In the second case, indicate one or two forces that could be exerted on the rod so- that at the instant shown the net force on it is zero, but the net torque on it is not zero.
