A boy has a mass of 45kg.
(i) Calculate his weight at a place where the acceleration due to gravity is 9.8m/s2.
(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.
(iii) At the Earth’s equator, the value of g is 0.3m/s2 less than at the poles. Taking gpole=9.83m/s2, find his weight at the equator.
