Question

Ken and Leah are trying to find the weight of a 3-pound rock on Mars. They can calculate it by multiplying the weight on Earth by what factor?

a) 0.25
b) 0.38
c) 1.50
d) 3.00

Answer 1

The weight of a 3-pound rock on Earth would be approximately 1.14 pounds on Mars when multiplied by the factor 0.38, representing Mars' gravitational force as a percentage of Earth's.

Step-by-step explanation:

To find the weight of a 3-pound rock on Mars, Ken and Leah need to multiply the weight of the rock on Earth by the gravitational factor of Mars compared to Earth's gravity. The gravity on Mars is approximately 38% of Earth's gravity. Therefore, the correct factor to multiply by is 0.38. So, the weight of a 3-pound rock on Earth would be equivalent to 3 pounds × 0.38 on Mars, which is approximately 1.14 pounds.
