A cast iron pan of mass 2.72 kg is used to cook food, then it is set aside to cool off before cleaning. The pan cools off from 320 degrees celcius to 70 degrees celcius after an unspecified amount of time. Find the amount of thermal energy released by the pan in this time. Use 0.460 kJ/kgK for the specific heat for cast iron

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
