A girl of mass m = 31 kg is standing on the edge of a very light merry-go-round. a distance r = 0,80 m from the center. The merrygoround spins with a constant angular velocity of w = 2.3 rad/s from in = 0 s to 1 = 3.2 5. Then. in order to stop the ride' the girl sticks her foot off the edge and drags it on the ground: the ride slows down and comes to a full stop at $2 : 7.5 s. (a) : 2 points Which of the following could be an angular position Vs. time graph for the girl? Circle the letter (A'BL', or D) to indicate your answer. {9 (b): 2 points Which of the following could be a centripetal acceleration vs. time graph for the girl"? Circle the letter (A,B,C, or D) to indicate your answer. (b): 2 points Which of the following could be a centripetal acceleration vs. time graph for the girl? Circle the letter (A,B,C_. or D} to indicate your answer. tall lad t' 4, it A (c): 4 points Calculate the net. torque T on the merry-go-round/girl system around its axis of rotation while the girl is dragging her foot. (d): 4 points What is the total number of rotations made by the merry-go-round' from t\" to 132? (e): 4 points How much thermal energy was produced while the girl was dragging her foot? Assume that her center of gravity did not change appreciably when she started to drag her foot
