Question

Suppose you have a weight of 830 N on Earth.

a. What is your mass?

b. What would be your weight on the Moon where ag = -1.6 m/s

Answer 1

As weight = mass x acceleration of gravity on earth, solve this equation for mass:

mass = 850 N/9.8m/s² = 86.7 kg. To find the weight on the moon, use

W = 86.7kg x 1.6m/s² = 140 N to two significant figures.
