1. The problem statement, all variables and given/known data A m = 5kg monkey swings on a vine the length l = 4m. His initial angle is theta = 25 degrees and he is moving at v = 2 m/s at the instant he begins his swing. a. What is the tension in the string at the bottom? b. What is the tension in the string at theta = 15 degrees? Here's a picture of the diagram, not necessary but makes it easier 2. Relevant equations I'm not really sure but here's a few. k = (1/2)mv^2 + mgh u = mgh 3. The attempt at a solution I have no idea how to involve the theta into the equation, so I can't even really get started. Sorry for being so bad at physics :( If it helps, at the moment we're learning about the conservation of energy, in kinetic and potential energy. Thank you for reading.
