Question

4. If a person weighs 500 N on Earth, what would she weigh on Jupiter, where the acceleration due to gravity is 26 m/s2? Show all work leading to your answer.

Answer 1

@iambatman

Answer 2

Any idea? What equations can be used.

Answer 3

Hint: Your weight changes on the planets, but your mass stays the same.

Answer 4

yeah M=Fe/Ge

Answer 5

Yes, F = ma, so solve for the mass, and then use the same formula again for the weight on Jupiter.

Answer 6

Weight = Force

Answer 7

so would it look like this 500 N /26 m/s2

Answer 8

No because 500N is the weight on Earth

Answer 9

What is the acceleration on earth?

Answer 10

9.8m/s/s

Answer 11

Yes, I should specify acceleration due to gravity.
9.8m/s^2

Answer 12

So you have the force and gravity, now solve for m on earth.

Answer 13

so 500N i will multiply by 26m/s2

Answer 14

No, why are you doing that? 500N is your weight on Earth, but you keep using Jupiter's acceleration due to gravity.

Answer 15

Find the mass, using Fearth = m*gearth

Answer 16

oh ok Fj=m*g

Answer 17

Yeah, but you need to find the mass first.

Answer 18

Mass doesn't change, weight does.

Answer 19

\[F_{earth} = ma \implies F _{earth}=mg_{earth}\] solve for m.

Answer 20

F = Mg
g = 9.81 m/sec^2 on earth
g = 26 m/sec ^2 on Jupiter

Woman's weight on Jupiter = 500/9.81 * 26

=1325.18 N

Answer 21

is that corrrect

Answer 22

Yeah that's correct, but I hope you understand what is going on in that equation.

Answer 23

thanks for the help
