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.
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.
