Question

Un cuerpo cuya masa es de 20 kg se lleva primero a la luna y luego a marte. Teniendo en cuenta el factor que liga masa y peso en marte es de 3,8 N/Kg

Answer 1

W = 76 N

Step-by-step explanation:

In this exercise you are asked to find the weight of the body.

Mass is a quantity that is invariant, it measures the same everywhere, the weight depends on where it is measured, a simple way to find the weight of a body is

W = g m

where g is the constant of the place, in this case we have the weight of the body on Mars and its mass which is constant on Earth and on Mars

W = 3.8 20

W = 76 N
