force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

Dancers do not often understand the physics and mathematics describing their movements‚ but they know how to execute them with grace. If ballerinas were not able to feel physics‚ they would fall over. Legs‚ arms and head are oscillating as they turn– moving back and forth in seemingly separate patterns. For dancers‚ everything must move in separate patterns‚ yet at the same time‚ move at the same rhythm. This presentation introduces the history‚ mathematics‚ and physics behind ballet. Ballet originated
