Astone is held at a height h above the ground. a second stone with four times the mass of the first one is held at the same height. the gravitational potential energy of the second stone compared to that of the first stone is

gravitational potential energy is given by formula

here we need to compare the gravitational potential energy of stone 2 with respect to stone 1

so we will say

given that

now we have

this could be newton#'s law of cooling. the cooling curve is exponential

i believe the answer is a hope it and is correct
