1. Calculate the potential energy, kinetic energy, mechanical energy, velocity, and height of the ball at the locations (1), (2), (3), and (4). Show your work below then insert your answers in the blank space provided (PE = , KE = etc.). PE is potential energy, KE is kinetic energy, and ME is mechanical energy.

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?
