Tarzan, who weighs 860 N, swings from a cliff att the end of a 20.0 m vine that hangs from a high tree limb and initially makes an angle of `22.0^(@)` with the vertical. Assume that an x axis extends horizontally away from the cliff edge and a y axis extends upward. Immediately after Tarzan steps of the cliff, the tension in the vine is 760 N. Just then, what are (a) the force on him from the vine in unit-vector notation and as (c) a magnitude and (d)an angle relative to the positive direction of Tarzon's acceleration just then ?

Explanation

(a) `(285N)hati+(705N)hatj,` (b) `(285N)hati-(155N)hatj,` ( c ) `324N,` (d) `-29.0^(@),` (e) `3.70" m"//"s"^(2),` (f) `-29.0^(@)`
