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

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
