Newtons law of gravity:
g=GMe/(radiusEarth + altitude)^2
k well i don't know what Me stands for or what the altitude is or how to find it.
You should know Newtons Law.
Me is mass of the Earth.
altitude is 220Km, given.
well my teacher cant teach so i dont. and i used the formula but i got a different answer then the back of the book. i don't get what im doing wrong.
g=GMe/(radius Earth+altitude)^2
g=(6.67x10*-11Nm^2/kg^2)x(5.98x10*24kg)/ (6.38X10*6m+0.22m)^2
g= (3.99x10*14Nm^2/kg)/(4.07x10*13m^2)
g=9.8N/kg
the back of the book says 9.1N/kg
