A piece of iron block moves across a rough horizontal surface before coming to rest. The mass of the block is 3.3 kg, and its initial speed is 4.0 m/s. How much does the block's temperature increase, if it absorbs 78% of its initial kinetic energy as internal energy? The specific heat of iron is 452 J/(kg- °C). O 0.0108 °C 0.0318 °C O 0.0180 °C O 0.0138 °C
