The radius of the earth is approximately 4,000 miles. The acceleration due to gravity is approximately 32 feet per square second. The mass of the earth is approximately 6 × 10^24 kilograms. Calculate the value of G in units of kilograms, meters, and seconds.

Answer 1

g=F/m=GMe/r^2

G=gr^2/Me

convert g from 32ft/s^2 to m/s^2 then convert rearth from miles to meters.
