At the surface of Jupiter's moon Io, the acceleration due to gravity is 1.81 m/s2m/s2 . A watermelon has a weight of 56.0 NN at the surface of the earth. In this problem, use 9.80 m/s2m/s2 for the acceleration due to gravity on earth.

Question:

At the surface of Jupiter’s moon Io, the acceleration due to gravity is g=1.81 m/s². A watermelon weighs 56.0 N at the surface of the earth.

(a) What is the watermelon’s mass on the earth’s surface?

(b) What would be its mass and weight on the surface of Io?

The answer to the question is

(a) 5.71 kg

(b) 10.34 N

Explanation:

The Weight of an object is given by

Weight = Mass × Acceleration due to gravity

on Earth the weight of the watermelon = 56 N

Therefore

The mass of the watermelon = = 56/9.8 = 5.71 kg

(b) On the surface of lo, the weight of the watermelon will be

Weight = Mass × Acceleration due to gravity

Where acceleration due to gravity on lo = 1.81 m/s²

Therefore the weight of the watermelon on lo = 1.81×5.7

= 10.34 N

that would be b i just took the test : )

the answer is a 3.8cm
