my answer: mv^2 / 2 + GMm/r

feedback: It appears that there may be a sign error associated with at least one term in your expression. Your answer is very close unfortunately there are additional terms in your equation that are not necessary.

E= KE + PE
E = (1/2)mC^(2) + mgz
Power = E/t

Total energy=Potential energy+Kinetic energy E Total = [1/2(mv2)] -(GMm/r)
