  2. ANNOUNCEMENTS

  3. 1 of 3 Each of the bodies below is released from rest. The curve shown is the path to which the body is constrained. Gravity is acting upon the bodies. There is no friction. Which of the bodies is moving with the greatest speed upon reaching the level marked? If they all have the same speed, respond “5.” 2 3 4 1 3

  4. 2 of 3 Body A falls freely to the level marked. Body B is a “pendulum.” It follows the circular path of motion because it is connected by a rod to a fixed point. Neglect sources of drag. The speed of body B upon reaching the marked level is Greater than that of A. Equal to that of A. Less than that of A. Zero. B A 4

  5. 3 of 3 A body is constrained to follow the track (as in the case of a roller coaster). The cart has just enough energy to “make it” over the top of the loop-dee-loop. The free-body diagram of the body at the top of the loop would look most like: 1 2 FN PATH OF MOTION PATH OF MOTION FN mg mg 3 4 FN PATH OF MOTION PATH OF MOTION mg mg 5
