Physics

Calcium, gold, iron, and sodium are all different kinds of metals. As a metal, they all share the common tendency of donating valence electrons instead of receiving them. Properties can either be physical or chemical, with physical being the color, size, texture. Chemical properties can be reactivity with water, or any other solvent.

$P_f = (5.51\times 10^7 \hat i + 5.67 \times 10^7) kg m/s$

Explanation:

Force on Asteroid due to Earth's gravity is given as

$F = \frac{Gm_1m_2}{r^2}\hat r$

now we know that

$F = \frac{(6.67 \times 10^{-11})(1200)(5.98\times 10^{24})(9.00\times 10^6\hat i + 10.00\times 10^6\hat j}{((9.00\times 10^6)^2 + (10.00\times 10^6)^2)^{1.5}}$

$F = 1769\hat i + 1965.5\hat j$

Now we can use impulse momentum theorem to find the final momentum of the Asteroid

$P_f = P_i + F\Delta t$

$P_f = 1200(4.30\times 10^4\hat i + 4.40\times 10^4\hat j) + (1769\hat i + 1965.5\hat j)(2.00\times 10^3)$

$P_f = (5.51\times 10^7 \hat i + 5.67 \times 10^7) kg m/s$
