Question

Tarzan, who weighs 820 \ 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 an
