Problem

A physics textbook of mass

2.5\,\text{kg}

is weighed at three different locations: • At the geographic pole where

g_{\text{pole}} = 9.83\,\text{m/s}^2

. • At the equator where

g_{\text{equator}} = 9.78\,\text{m/s}^2

. • On the surface of the Moon where

g_{\text{moon}} = 1.6\,\text{m/s}^2

. a. (a) Calculate the weight of the textbook at the pole. b. (b) Calculate the weight of the textbook at the equator. c. (c) Determine the ratio of the textbook’s weight at the pole to that at the equator. d. (d) Calculate the weight of the textbook on the Moon and state, in comparison with its weight at the pole, by what factor it is smaller.
