What would the 5.00 slug mass in Example 2.1 weigh on the Moon where the acceleration of gravity is only 1/6 of that on Earth?

Assume that on the surface of the Earth, g = 9.81 m/s² = 32.2 ft/s² (i.e., each to three significant figures). Make sure you are reporting the solution to the proper number of significant figures.

Example 2.1

Suppose you define a mass unit called the slug—a rather ugly word for a mass that accelerates by exactly 1 ft/s² when a force of exactly 1 lb is applied to it.

What is the weight of a mass of 5.00 slug? (Weight is the term for a force in the Earth’s gravitational field, which produces an acceleration of 32.2 ft/s².)

Equation (2.3) is the applicable principle for this problem:

 

Hence
