Jupiter's gravitational field at the surface is approximately three times that of the earth. A person weighing 120 lb. on the earth's surface would weigh how much on Jupiter?

Wt. = 3 * 120 = 360 Lbs.

To find out how much a person would weigh on Jupiter, we need to consider the difference in gravitational forces between Jupiter and Earth.

We know that the person weighs 120 lb on Earth's surface. We also know that Jupiter's gravitational field at the surface is approximately three times that of Earth. This means that the gravitational force on Jupiter is three times stronger than on Earth.

To calculate the person's weight on Jupiter, we can use the following equation:

Weight on Jupiter = Weight on Earth × Jupiter's gravitational field strength

Weight on Jupiter = 120 lb × 3

Weight on Jupiter = 360 lb

Therefore, the person would weigh 360 lb on Jupiter.
