No.So.

##E_1##=##m##g##h##+½mv1^{2}

##E_2## = ½(m+50) v2^{2}

then

##E_1## = ##E_2##

##E_1 = Mgh_1 = \frac 1 2 Mv_1^2##

##E_1 \ne E_2##

##E_2 = (M + m)gh_2 = \frac 1 2 (M+m)v_2^2##

Where ##M## and ##m## are the masses of Tarzan and Jane.

I suspect this problem is a lot harder than the ones you are used to. Solving this problem involves a strategy, not just plugging numbers into an equation!
