Tarzan, whose mass is 95.0 kg, swings from a 3.10 m vine that is horizontal when he starts. At the bottom of his arc, he picks up 60.0 Jane in a perfectly inelastic collision. What is the height of the highest tree limb they can reach on their upward swing?

I believe I need to use both inelastic collision equation
m1v1i +m2v2i = (m1 + m2)vf
as well as conservation of energy
KEi + PEi = KEf + PEf
(1/2)mvi^2 + mghi = (1/2)mvf^2 mghf
My problem is that I'm not sure how to use the inelastic collision equation because if I assume Tarzan starts at rest then the left side is equal to 0 but if I assume he has an initial velocity then I wind up with two unknowns, v1i and vf.

finding the derivitive of 2s^(3/2)

so far i've done (3/2) - 1 = 1/2

my answer is s^(1/2) but the answer to the problem is 3s^(1/2)..i'm not sure where the 3 comes from

Determine which is the less harmful action for the painter: to let go of the ladder right away and fall to the ground, or to hang on to the ladder all the way to the ground
