In 1985 benitoite became the california "state gemstone." found only in a tiny mine near coalinga, california, it is a silicate of barium and titanium with trace impurities that cause a range of hues from colorless to blue to pink. its general formula is bati(sio3)3. if a 15-carat stone were pure bati(sio3)3, how many moles of oxygen would it contain? (there are exactly 5 carats per gram.)

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
