tarzan has a mass of 100 kg and is 200m above the group and wants to slide down a nearby vine. the vine can only hold 400n without breaking. assuming he starts from rest and moves with a constant acceleration what is the longest time it can take for Tarzan to reach the ground?

Physics 
bobpursley,
tension= mgma
400N=100(9.8a)
solve for a. Then,
200m=at solve for t.
