Answer:
the weight of the astronaut on Earth is 1209.88 N
Step-by-step explanation:
Given;
weight of the astronaut, W = 200 N
acceleration due to gravity on moon, g = 1.62 m/s²
Apply Newton's second law of motion to determine the mass of the astronaut;
F = ma = mg
m = F/g
m = 200 / 1.62
m = 123.457 kg
The weight of the astronaut on Earth is calculated as follows;
F = mg
where;
g is acceleration due to gravity on Earth = 9.8 m/s²
F = 123.457 x 9.8
F = 1209.88 N
Therefore, the weight of the astronaut on Earth is 1209.88 N
