.Graded problem 1 (10pt) A CT scan uses a rotating X-ray source mounted on a circular ring to capture three dimensional images of a body (see Figure 43.2 on page 521 of the textbook). One rotation of the X-ray source produces one sliced image of the body. A specific CT scan machine has a circular ring with diameter 80 cm (radius 40 cm), and the mass of the X- ray source mounted on the circular ring is 38 kg. The time it takes to capture one sliced image is 350 milliseconds. Assume that the X-ray source rotates at a constant speed. (a) What is the translational speed of the X-ray source in m/s? (2 pt) (b) What is the angular speed of the X-ray source in rad/s? (2 pt) (c) What is the magnitude of the centripetal force on the X-ray source? (2 pt) (d) How many degrees does the X-ray source turn in 100 milliseconds? (2 pt) (e) What is the frequency of the rotation of the X-ray source? (2 pt)
