A person weighing 70 kg holds a box weighing 20 kg on his shoulders.

A person weighing 70 kg holds a box weighing 20 kg on his shoulders. With what force does a person press on the ground?

To determine with what force a person presses on the ground, given that his mass is 70 kg, and he is holding a box weighing 20 kg on his shoulders, you must first find the sum of both bodies, since the pressure of the legs of a person with a load on his shoulders will be higher: 70 + 20 = 90 (kg), we get m = 90 kg. The force with which a person presses on the ground arises as a result of the action on him (together with the box) of gravity and is determined by the formula: F = m · g, where g = 9.8 m / s ^ 2. then F = 90 kg 9.8 m / s ^ 2; F = 882 N.
Answer: a person presses on the ground with a force of 882 N.
