Problem

An instrument package of mass

4.0\,\text{kg}

is deployed on the Moon, where the gravitational field strength is

1.6\,\text{m/s}^2

. If the coefficient of kinetic friction between the package and the lunar surface is

0.50

, what is the magnitude of the kinetic friction force on the package as it slides? a)

6.4\,\text{N}

3.2\,\text{N}

12.8\,\text{N}

20\,\text{N}
