As Fig. 8-44 shows, a 4.5 kg block is accelerated by a compressed spring whose spring constant is 640 N/m. After leaving the spring at the spring's relaxed length, the block travels over a horizontal surface, with a coefficient of kinetic friction of 0.25, for a distance of 5.9 m before stopping.
(a) What is the increase in the thermal kinetic energy of the block floor system?
(a) All the energy will dissipate and become heat after the block stops. Therefore, the increase of thermal energy is equal to the initial total energy. ...
