Answer:

[tex]4.4\cdot 10^{11} kg m/s[/tex]

Explanation:

The relativistic momentum of an object is given by

[tex]p=\gamma m_0 v[/tex]

where:

[tex]\gamma = \frac{1}{\sqrt{1-\frac{v^2}{c^2}}}[/tex] is the relativistic factor, with v being the speed and c being the speed of light

m0 is the rest mass of the object

v is the speed

In this problem, we have

m = 1500 kg is the rest mass

v = 0.700 c is the speed of the meteorite

So we find

[tex]\gamma = \frac{1}{\sqrt{1-\frac{(0.700 c)^2}{c^2}}}=1.4[/tex]

And so the momentum is

[tex]p=(1.4)(1500 kg)(0.7\cdot 3\cdot 10^8 m/s)=4.4\cdot 10^{11}kg m/s[/tex]
