Im confused there is an example in image 1 i dont know how im too lazy to do it

Atomic weight =

(AMU*Abundance%)+(AMU*Abundance%)

so thats

(62.9296*69.15/100)+(64.9278*30.85/100)

43.5158184+20.0302263

≈63.55 amu

hope i helped

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.
