How much would a 77.7 kg person weigh (a) on Earth's Moon, where the acceleration of gravity is 1.63 m/s2, and (b) on Mars, where the acceleration of gravity is 3.77 m/s2?

The answer to your question is below

Explanation:

Data

mass of the person = 77.7 kg

gravity on the moon = 1.63 m/s²

gravity on mars = 3.77 m/s²

Process

To find the weight of a person, use Newton's second law.

Formula

        Force = mass x acceleration  but  Weight = mass x gravity

a)  

        Weight = 77.7 x 1.63

        Weight = 126.65 N

b)  

        Weight = 77.7 x 3.77

        Weight = 292.93 N
