The weight of an object of each planet is proportional to the force of gravity in the planets atmosphere. The force of gravity on planet earth is approximately 9.8 1MS2. The force of gravity on Mars is 0.3 8MS2 if he weighs 128 pounds on earth, how much would he weigh on Mars Round to the nearest hundredth
To find the weight on Mars, we can set up a proportion using the force of gravity on Earth and the force of gravity on Mars.
Let x be the weight on Mars.
Using the proportion: (force of gravity on Earth)/(weight on Earth) = (force of gravity on Mars)/(weight on Mars)
(9.8 1 MS2) / (128 pounds) = (0.38 MS2) / (x pounds)
Cross multiplying, we get:
9.8 MS2 * x pounds = 0.38 MS2 * 128 pounds
9.8x = 48.64
Dividing both sides by 9.8:
x = 4.96
Therefore, he would weigh approximately 4.96 pounds on Mars.
