Potential energy is a stored energy, which  is caused by the gravitational pull of the earth, that is why when you go up the potential energy will increase. to calculate the mass, just substitute the given to the formula and solve for m

PE = m x g x h
4620 = m x 9.8 x 8.4
m = 4620 / ( 9.8 x 8.4)
m = 56.1 kg is thr mass of the man

Answer:

the answer is 56kg all you have to do is round 56.1 to the nearest whole number
