Answer: Skier 1 will have more potential energy because he is higher than skier 2
Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.
P.E=
m= mass of the body
g= acceleration due to gravity
h= height of body
Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.
