Answer 2

Answer:

623.6N

Explanation:

There are 2.2 pounds in one kilogram, so you must divide 140 lb by 2.2 to convert the units to kilograms.

140/2.2 = 63.6 kg

The gravitational force also known as weight would equal mass times acceleration due to gravity.

Fg = (63.6 kg)(9.8 m/s^2) = 623.6N
