Research any historical cases where the Federal Government has passed a federal law that overturns state law? (Hint: Think about civil rights legislation and state laws discriminating against certain individuals.)

Next, consider this factual scenario:

Clarence owns land in Georgia. He plans on extracting a rare type of mineral from the land and selling it to baseball teams to rub on the baseball to reduce the bright glare of the ball when batting. The Federal Government passes a law that prohibits the sale of this type of product. Clarence is outraged that the Federal Government will not allow him to collect and sell mud from his own land. Does the Federal Government have authority to prohibit Clarence's intended business? Explain.
