Answer:

1181.63 m

Explanation:

Assume : specific heat for copper = 386 J/kg.k

Determine the height a 300k  cu ball can lift itself after transforming all its thermal energy to work

Total thermal energy of ball =  386J/kg.k * 300 k

                                                = 115800 J

when we convert to potential energy ( work )  applying the law of conservation of energy

11580 J = mgh

11580 = 1 * 9.8 * h       ( note m = 1 because the cu is just 1 unit )

∴ h ( height attained ) = 11580 / 9.8   = 1181.63 m
