This is problem from the extension section from my Gr.12 physics text book 1. The problem statement, all variables and given/known data Tarzan (m=100kg) hold one end of an ideal vine (infinitely strong, completely flexible, but having zero mass) The vine runs horizontally to the edge of a cliff, then vertically where Jane (m=50kg) is hanging on,above a river filled with crocodiles. A sudden sleet storm has removed all friction. Assuming that Tarzan hangs on, what is the acceleration toward the cliff edge? 2. Relevant equations Newton's laws of motion. Projectile motion. 3. The attempt at a solution Horizontal & vertical distance is not given, making it absolutely difficult to apply projectile applications. I know that for Tarzan (horizontally) Fnet = Tcosθ (vertically) Fnet = Tsinθ - Fg b/c he will be moving on the vine. I know that for Jane, 0=T-Fg, since she is in a stable position T=Fg I am completely lost on this question, can anybody help me or hint to me something about the solution.
