80 kg Tarzan grabs a vine to swing to another tree. a. As Tarzan swings from point A to point B, describe qualitatively how the tension in the vine changes and why. 8 m BC b. At point B he is swinging at 7 m/s and the vine is 8 meters long. How hard does he have to hang on to the vine to keep from slipping off? c. A moment later, at point C, the vine catches on a branch, reducing the radius of the swing to 2 m. If Tarzan is still traveling at 7 m/s, how hard does he now have to hold on to the vine? d. If Tarzan slips off at point C what will be the path he takes? (Sketch the path on the diagram.) How does this path differ from circular motion?
