Question

What is the magnitude Of the force of gravity on a person who has a mass of 80.0 kg?

Answer 1

784 N

Step-by-step explanation:

Answer 2

The magnitude of the force of gravity on that person is 784 Newton.

Step-by-step explanation:

The weight is a force acting on an object as a consequence of gravity and is defined as:

`W = m \cdot g` (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:

`W = (80.0 kg)(9.8m/s^(2))`

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])

`W = 784 Kg.m/s^(2)`

But
`1 N = kg.m/s^(2)`

`W = 784 N`

Therefore, the magnitude of the force of gravity on that person is 784 Netwon.
