Please refer to the picture with the formulas and constants that need to be used in this problem. Harzan wants to swing from one bank of the river to the other using an overhaning vine. As he swings, he traces out an arc of a circle. Part 1) Please draw and label a free body diagram of Harzan at the bottom of the swing. Answer: we have to discuss the motion of the swinging person Part 2) What forces act as the radial force in the circular motion? Answer: In the radial direction centrifugal force will act as a source of tension Part 3) Is this uniform circular motion? Explain Answer: The motion is similar to that of a pendulum, thus the vine-swinger system acts like a physical pendulum, the motion will not be uniform circular. Part 4) The vine is 6.2 m long, and Harzan's mass is 85 kg. At the bottom of his swing, he is travelling at 4.3 m/s. What is the magnitide of the radial acceleration that Harzan experiences? Part 5) How much tension must the vine support in order to safely…
