physics work 2

Force of gravity=(G*mass1*mass2)/radius^2 

Assume that you have a mass of 45.0 kg and Earth has a mass of 5.97 × 1024 kg. The radius of Earth is 6.38 × 106 m. What is the force of gravitational attraction between you and Earth? Use G = 6.67 × 10-11 N·m2/kg2.

G = 6.67 x 10^-11
mass 1: 45
mass 2: 5.97 x 10^24
radius: 6.38x10^6

(6.67 x 10^-11) x (45)x(5.97 x 10^24) = 1.7918955 x 10^16/ (6.38x10^6)^2  =440.221573098
