6-136.

picDue to differences in gravity, a -pound person on Earth would weigh about  pounds on Mars and pounds on the moon.  Homework Help ✎

  1. What would a -pound person on Earth weigh on Mars? Explain your reasoning with words or a diagram.

    How much would a -pound person on Earth weigh on Mars? Note that pounds is half of 100 pounds, therefore the person's weight on Mars and on the moon should be halved.

    Now note that is triple . What should the person's weight on Mars be?

    pounds.

  2. What would a -pound person on Earth weigh on the moon? Explain your reasoning with words or a diagram.
