What is the weight of a 60 kg astronaut on earth?

The weight of an object is calculated using the formula ( \text{Weight} = \text{mass} \times \text{gravity} ). For a 60 kg astronaut on Earth, where the acceleration due to gravity is approximately ( 9.81 , \text{m/s}^2 ), the weight would be ( 60 , \text{kg} \times 9.81 , \text{m/s}^2 = 588.6 , \text{N} ). Therefore, the astronaut weighs about 588.6 newtons on Earth.
