Suppose that you suspend a 10.0kg mass of iron from a height of 200metes. the outside temperature is 300Ka. What is the kinetic energy of the mass just before it hits the ground?b. What is the velocity of the iron mass?c. What is the final temperature of the mass ifall of its kinetic energy at impact is transformes into internal energy? (c sub p=25.1mol -1k-1
