On the moon the acceleration of gravity is 1.6m/s2. What does a 73 kg space suit weigh? (Answer to the nearest hundredth)

Answer 1

F = ma = (73 kg)(1.6 m/s²) = 116.8 N

Answer 2

Weight is the force of gravity on an object. Therefore the equation for this is:

F = ma

with the acceeration on the moon being 1.6 m/s²

To determine the weight of a 73 kg person, we substitute in the values:

Weight = F = 70 kg x 9.8 m/s² = 116 kg(m)/s²

The unit kg(m)/s² is also known as a Newton. So the person's weight would be 116.8 N.
