the earth moves at a speed of 2.95*10^4m/s and has a mass of 6.0*10^24. calculate the momentum of the earth

Sagot :

Given:

the speed of the earth is

[tex]v=2.95\times10^4\text{ m/s}[/tex]

mass of the earth is

[tex]m=6.0\times10^{24}\text{ kg}[/tex]

Required:

momentum of the earth needs to be calculated.

Explanation:

To calculate the momentum of the earth we will use momentum formula that is given as

[tex]P=mv[/tex]

here P is momentum, m is the mass of the earth and v is the velocity of the earth.

plugging all the values in the above relation. we get,

[tex]\begin{gathered} P=6.0\times10^{24}\text{ kg }\times2.95\times10^4\text{ m/s} \\ P=\text{ 17.7 }\times10^{28}\text{ kg m/s} \end{gathered}[/tex]

Thus, the momentum of the earth is

[tex]P=\text{17.7}\times10^{28}\text{kg\frac{m}{s}}[/tex]
