Determine the mass of an object that has a weight of (a) 20 mN, (b) 150 kN, and (c) 60 MN. Express the answer to three significant figures.
Applying Eq. 1–3, we have
a) m = \frac{W}{g} = \frac{20 (10^{-3}) Kg ·m/s^{2} }{9.81 m/s^{2} } = 2.04 g
b) m = \frac{W}{g} = \frac{150 (10^{3}) Kg ·m/s^{2} }{9.81 m/s^{2} } = 15.3 Mg
c) m = \frac{W}{g} = \frac{60 (10^{6}) Kg ·m/s^{2} }{9.81 m/s^{2} } = 6.12 Gg
