A(n) 4.4-kg copper block is given an initial speed of 2.7 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, °C (b) What happens to the remaining energy? O It becomes chemical energy. O It vanishes from the universe. It is so minute that it doesn't factor into the equation. O It is absorbed by the horizontal surface on which the block slides. ( Need Help? Read it
