A 203 rad dose of radiation is administered to a patient in an effort to combat a cancerous growth. Suppose that all of the energy deposited is absorbed by the growth.
A weightlifter has been given a barbell to lift. One end has a mass of 5.05 kg while the other end has a mass of 5.20 kg. The bar is 0.20 m long. (Consider the bar to be massless, and assume that the masses are thin disks, so that their centers of ma..
