3. the density, d of an x-box 1 can be found by using the following formula d = m, where mis
the mass of the x-box and v is its volume. what is the density of the x-box that has a mass of
73,430 kilograms and a volume of 7m3?

d = 10490 kg/m³

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Mass of box = 73430 Kg

Volume = 7 m³

density of box = ?

Solution:

d = m/v

d = 73430 Kg/7 m³

d = 10490 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.
