A probe sent to the surface of Mars uncovers a pure platinum disc inscribed with the message, "We'll be right back" (in Martian, of course!). The disc is 3 inches thick and 06 meters in diameter. The density of platinum is 21,450 kgm3. What is the mass of the platinum disc in pounds (lbm)? lbm The Martian acceleration due to gravity is 3.61 ms2 while Earth's gravitational constant is 32.2 fts2. What is the Earth weight of the disc in Newtons?
