At the surface of Jupiter's moon Io, the acceleration due to gravity is 1.81 m/s2 . A watermelon has a weight of 40.0 N at the surface of the earth. In this problem, use 9.80 m/s2 for the acceleration due to gravity on earth.Part A

What is its mass on the earth's surface?

Part B

What is its mass on the surface of Io?

Part C

What is its weight on the surface of Io?

Answer :

Answer

acceleration due to gravity on Jupiter's moon,g' = 1.81 m/s²

weight of water melon on earth, W = 40 N

acceleration due to gravity on earth, g = 9.8 m/s²

a) Mass on the earth surface

    [tex]M = \dfrac{W}{g}[/tex]

    [tex]M = \dfrac{40}{9.8}[/tex]

           M = 4.08 Kg

b) Mass on the surface of Lo

 Mass of an object remain same.

  Hence, mass of object at the surface of Lo = 4.08 Kg.

c) Weight at the surface of Lo

   W' = m g'

   W' =4.08 x 1.81

   W' = 7.38 N
