The weight of an object on each planet is proportional to the force of gravity in that planet's atmosphere. The force of gravity on planet Earth is approximately 9.81 m/s². The force of gravity on Mars is 0.38 m/s². If Hill weighs 128 pounds on Earth, how much would he weigh on Mars? Round to the nearest hundredth.

1 answer

To find Hill's weight on Mars, we can use the ratio of the forces of gravity between Mars and Earth.

Weight on Mars = (Gravity on Mars / Gravity on Earth) * Weight on Earth

Weight on Mars = (0.38 m/s² / 9.81 m/s²) * 128 pounds

Weight on Mars = (0.03875) * 128 pounds = 4.96 pounds

Hill would weigh approximately 4.96 pounds on Mars.
