What is the mass of a person if at a height of 10m he has a potential energy of 5.5 kJ?

Let’s remember the formula for potential energy:
En = m * g * h, where m is the mass of the body, En is the potential energy of the body, h is the height to which the body was lifted
Then m = Ep / (g * h) = 5500/100 = 55kg
