Problem

A maintenance crew prepares to ship a sealed toolbox from Earth to a small asteroid mining site. The toolbox has a measured mass of

12\,\text{kg}

on Earth. (a) Determine the gravitational force exerted on the toolbox at Earth’s surface. Use

g=9.8\,\text{N}\!/\!\text{kg}

. (b) Express the magnitude of this force in pounds-force, given that

1\,\text{lb}_{\!f}=4.45\,\text{N}

. (c) Upon arrival at the asteroid, the local gravitational field strength is

0.25\,\text{N}\!/\!\text{kg}

. Calculate the gravitational force that the asteroid exerts on the same toolbox.
