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 vineis 760 N. Just then,
Part A: What is the force on him from the vine in unit-vector notation?
Part B: What is the net force on him in unit-vector notation and as
A - A magnitude and
B - An angle relative to the positive direction of the x axis?
Part C: What is the magnitude of Tarzan's acceleration?
Part D: What is the angle of Tarzan's acceleration?
Please show complete calculation thank you!
