Question

A sledgehammer weighs 18 pounds on earth and 4 pounds on the planet namar. based on the numbers given, your weight on namar would be about _____ times your weight on earth.

Answer 1

My weight would be (4/18) = 22.2% (rounded) of my Earthly weight.
I'm going to stop there, and not mention what that would be.

Answer 2

2 by 9 (2/9) times

Step-by-step explanation:

The weight of an object depends on the acceleration due to gravity of the planet on which the object is.

`W_e`= Weight of sledgehammer on Earth = 18 pounds

`W_n`= Weight of sledgehammer on planet Namar = 4 pounds

Dividing the values we get

`(W_e)/(W_n)=(18)/(4)\\\Rightarrow W_n=(4)/(18)W_e\\\Rightarrow W_n=(2)/(9)W_e`

So, your weight on Namar would be 2 by 9 (2/9) times your weight on Earth.
