Question

ment PRINTER VERSION <BACK NEX Chapter 05, Problem 023 Tarzan, who weighs 816 N, swings from a diff at the end of a 16.9 m vine that hangs from a high tree limb and initially makes an angle of 19.6° with the vertical. Assume that an x axis points horizontally away from the cliff edge and a y axis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is 769 N. Just then, what are (a) the force from the vine on Tarzan in unit-vector notation, and (b) the net force acting on Tarzan in unit- vector notation? What are (c) the magnitude and (d) the direction (measured counterclockwise from the positive X- axis) of the net force acting on Tarzan? What are (e) the magnitude and (f) the direction of Tarzan's acceleration just then? j Units j Units (a) Number (b) Number i+ (c) Number Units (d) Number Units (e) Number Units (1) Number Units Click if you would like to show Work for this question: Open Show Work SHOW HINT
