Final answer:

The force of gravitational attraction between a person and the Earth can be calculated using Newton's universal law of gravitation.

Step-by-step explanation:

The force of gravitational attraction between two objects is given by Newton's universal law of gravitation:

F = G* (m1*m2)/r^2

Where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers of mass.

Using the given values, we can calculate the gravitational force between a person with a mass of 60.0 kg and Earth:

F = (6.674 × 10^-11 N·m²/kg²)*(60.0 kg)*(5.972 × 10^24 kg)/(6.38 × 10^6 m)^2

F = 588.96 N

This means that the force of gravitational attraction between a person with a mass of 60.0 kg and Earth at its surface is approximately 588.96 N.
