Question

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

Answer 1

Given:

the speed of the earth is

`v=2.95*10^4\text{ m/s}`

mass of the earth is

`m=6.0*10^(24)\text{ kg}`

Required:

momentum of the earth needs to be calculated.

Step-by-step explanation:

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

`P=mv`

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,

`\begin{gathered} P=6.0*10^(24)\text{ kg }*2.95*10^4\text{ m/s} \\ P=\text{ 17.7 }*10^(28)\text{ kg m/s} \end{gathered}`

Thus, the momentum of the earth is

`P=\text{17.7}*10^(28)\text{kg(m)/(s)}`
