18. We note that the rope is 22.0° from vertical – and therefore 68.0° from horizontal. (a) With T = 760 N, then its components are ˆˆ ˆ ˆ cos 68.0 i+ sin 68.0 j=(285N)i+(705N) j TT T ° G . (b) No longer in contact with the cliff, the only other force on Tarzan is due to earth’s gravity (his weight). Thus, net ˆ ˆ ˆ (285 N) i+(705 N) j (820 N) j (285N)i (115 N) j.
