Given: g = 6.67259 × 10−11 n m2 /kg2
a 944 kg meteor comes in from outer space and impacts on the a moon’s surface (this moon is not necessarily the earth’s moon). the mass of this moon is m = 7 × 1022 kg, and the radius of this moon is r = 1.5 × 106 m. how much work is done by the moon’s gravitational field? answer in units of j.

Work done W 2.938*10^9 J

Explanation:

given data:

mass m = 944 Kg

Mass of moon M = 7*10^22 Kg

Radius of the moon R = 1.5*10^6 m

gravitational constant G = 6.67*10^{-11} Nm^2/Kg^2

we know that work done is given as

Work done

                      = 2.938*10^9 J

answer; how far out of place which the object finished relative to the starting location;

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
