Tarzan, who weighs740N, swings from a cliff at the end of a19.0m vine that hangs from a high tree limb and initially makes an angle of25.0°with the vertical. Assume that anxaxis extends horizontally away from the cliff edge and ayaxis extends upward. Immediately after Tarzan steps off the cliff, the tension in the vine is671N.
(a) At the moment of takeoff, what is the force on Tarzan from the vine, in unit-vector form?
=N
(b) At that moment, what is the net force on Tarzan, in unit-vector form?
net=N
(c) What is the net force on Tarzan, as a magnitude and angle relative to the positive direction of thexaxis?
