A(n) 1.2-kg copper block is given an initial speed of 3.9 m/s on a rough horizontal surface. Because of friction, the block finally comes to rest. (a) If the block absorbs 85% of its initial kinetic energy internal energy, calculate its increase in temperature. Your response differs significantly from thế correct answer. Rework your solution from the beginning and check each step carefully.°C (b) What happens to the remaining energy? O It is absorbed by the horizontal surface on which the block slides. O It is so minute that it doesn't factor into the equation. O It becomes chemical energy. O It vanishes from the universe.

Question
A(n) 1.2-kg copper block is given an initial speed of 3.9 m/s on a rough horizontal surface. Because of friction, the block finally comes to rest. (a) If the block absorbs 85% of its initial kinetic energy as internal energy, calculate its increase in temperature. Incorrect: Your answer is incorrect. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.°C (b) What happens to the remaining energy?
