A heat engine absorbs 8,500 J of thermal energy from a hot reservoir. During one cycle, the engine performs 2,400 J of useful mechanical work on its surroundings and releases thermal energy to a cold reservoir. Determine the thermal energy released to the cold reservoir and calculate the efficiency of the engine. Show your working.
