Answer:
1181.63 m
Step-by-step 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
