At the surface of Jupiter's moon Io, the acceleration due to gravity is 1.81 m/s2 . A watermelon has a weight of 54.0 N at the surface of the earth. In this problem, use 9.80 m/s2 for the acceleration due to gravity on earth. What is its mass on the earth's surface?

Answer:

[tex]m=5.51Kg[/tex]

Explanation:

The weight of an object on Earth is given by [tex]W=mg[/tex], so we can calculate its mass by doing [tex]m=W/g[/tex], which for our values is:

[tex]m=(54N)/(9.8m/s^2)=5.51Kg[/tex]

Nothing is being asked about Io but if one wanted to know the weight W' of the watermelon there one just have to do:

[tex]W'=ma=(5.51Kg)(1.81m/s^2)=9.97N[/tex]
