You drive an automobile of mass 2.10*10(3) kg from sea level to the top of a mountain 2.05km high? What is the automobiles' change in weight?
mass m = 2.10*10^(3) kg
h = 2.05 km = 2.05*10^3 m
Radius of earth Re = 6400 km
Gravitaional acceleration at the earth's surface g = 9.81 ...
This solution includes four steps of calculations.
