1. The problem statement, all variables and given/known data http://img256.imageshack.us/my.php?image=b911om5.jpg sin30= .50 sin60= .87 cos30= .87 cos60= .50 tan30= .58 tan60= 1.73 A 5.0 kilogram monkey hangs initially at rest from two vines. A and B, as shown above. Each of the vines has length 10 meters and negligible mass. For parts c and d: The monkey releases vine A and swings on vine B. Neglect air resistance. c. Determine the speed of the money as it pass through the lowest point of it's first swing. d. Determine the tension in vine B as the monkey passes through the lowest point of its first swing. 2. Relevant equations Centripetal force? m(v^2/r) 3. The attempt at a solution Completed parts a and b. Force diagram and tensions in each vine before release. T1= 9N and T2= 5.13N I'm not sure as what I am to do... I'm thinking that it has something to do with centripetal force but not sure cause he is swinging.
