Answer:
2 by 9 (2/9) times
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
\(\frac{W_e}{W_n}=\frac{18}{4}\\\Rightarrow W_n=\frac{4}{18}W_e\\\Rightarrow W_n=\frac{2}{9}W_e\)
So, your weight on Namar would be 2 by 9 (2/9) times your weight on Earth.
