Answer:
The weight of the person on the Earth's surface is 784N
Solution:
The weight and mass are separate things. The weight of the person includes the gravitational acceleration along with the mass of the person as per Newton’s second law.
So, [tex]Weight = Mass\times GravitationalAcceleration[/tex]
Here the mass = 80 kg
We know the gravitational acceleration = [tex]9.8 m/sec^2[/tex]
So the weight of the person = [tex]Mass \times Gravitational acceleration = (80\times9.8)N = 784N[/tex]
