Tarzan, who weighs 820 N, swings from a cliff at 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 off 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 the net force on him (b) in unit-vector notation and as (c) a magnitude and (d) an angle relative to the positive direction of the x axis? What are the (e) magnitude and (f) angle of Tarzan’s acceleration just then?

Question
Tarzan, who weighs 820 N, swings from a cliff at 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 off 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 the net force on him (b) in unit-vector notation
and as (c) a magnitude and (d) an angle relative to the
positive direction of the x axis? What are the (e) magnitude and
(f) angle of Tarzan’s acceleration just then?
