Consider a pure-iron cannon ball of known mass 4 kg being shot from a cannon. Initially, the ball is not moving, is located at an elevation of 1m relative to the ground, and is at the surrounding temperature of 20 C. One second after being fired from the cannon, the ball is moving at a scalar velocity of 250 m/s at an elevation of 1.5 m and a temperature of 100C. Report answers in units of Joules. Assume c = 447 J/kg-K Determine the change in potential energy. b. Determine the change in kinetic energy. c. Determine the change in internal energy. d. Determine the change in total energy.
