Problem

A boy has a mass of

45\,\text{kg}

. a. (i) Calculate his weight at a place where the acceleration due to gravity is

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

. b. (ii) The boy travels to the Moon where the acceleration due to gravity is one-sixth that on the Earth. Calculate his weight on the Moon. c. (iii) At the Earth’s equator, the value of

g

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

less than at the poles. Taking

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

, find his weight at the equator.
