What is the density of a 700 kg object with a volume of 649 m3? (density: d = ) 0.927 kg/m3 .4543 kg/m3 1.079 kg/m3 4.543 kg/m3

The density  of 700 kg object  with  a volume of 649 m³  is 1.079  kg/M³

 calculation

  This problem is solved using density  = mass /volume   formula

mass= 700 kg

volume= 649 m³

density is therefore =  700 kg / 649 m³  = 1.079 kg/m³

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.
