I need help solving this problem. Can you help me!! Please tell me the steps and what formula. This is my last problem and I need help!! Please and thank you

Tarzan is hanging straight down by a vine on the edge of a cliff when a very scared Jane, being chased by wild monkeys, runs at 5.0 m/s into and grabs onto him causing them both to swing out over the edge of the cliff and up to a point that is 2.1 degrees above the cliff. If the tension in the vine when they are both on it, is 1275.3 N and Tarzanʼs mass is 2.25 times that of Janeʼs, determine the horizontal distance over the edge of the cliff that they traveled.

First, draw a picture.

Do you have a formula in mind?

that's what I have so far... is that right?? I just need to plug in the numbers if its right

m=Jane's mass
M is the combined
using conservation of momentum
m*5=M*v
or
v=5/3.25
and
.5*M*v^2=M*g*h
or
h=v^2/(2*g)
or
h=25/(2*g*3.25^2)
and
Tan2.1=h/d
where d is the horizontal distance over the edge

d=h/tan2.1
