Answer:
The magnitude of the force of gravity on that person is 784 Newton.
Explanation:
The weight is a force acting on an object as a consequence of gravity and is defined as:
[tex]W = m \cdot g[/tex] (1)
Where m is the mass and g is the value of the gravity.
Finally, making the assumption that the person is in the Earth and using equation 1 it is gotten:
[tex]W = (80.0 kg)(9.8m/s^{2})[/tex]
Remember that the value of g change in function of the radius and mass of the planet ({tex]g = \frac{G\cdotM}{R^{2}}[/tex])
[tex]W = 784 Kg.m/s^{2}[/tex]
But [tex]1 N = kg.m/s^{2}[/tex]
[tex]W = 784 N[/tex]
Therefore, the magnitude of the force of gravity on that person is 784 Netwon.
