Homework Statement
Io (pronounced “EYE oh”) is one of Jupiter’s moons discovered by Galileo. Io is slightly larger
than Earth’s Moon.
The mass of Io is 8.92*1022 kilograms
and the mass of Jupiter is 1.9*1027
kilograms. The distance between the
centers of Io and Jupiter is r = 4.22*10 meters.
1. Calculate the magnitude of the gravitational force of
attraction that Jupiter exerts on Io.
2. Calculate the magnitude of the acceleration of Io due
to the gravitational force exerted by Jupiter.
Homework Equations
Fg = G m1 m2/r2
Io = m1 = 8.92*1022
Jupiter = m2 = 1.9*1027
r = 4.22*10
G = 6.67*10-11
The Attempt at a Solution
1. Fg = (6.67*10-11)(8.92*1022)(1.9*1027) / (4.22*108)2
= 6.36*1022N
2. How can i find the acceleration of Io?
Do i use F=ma => a=F/m => a = (6.35*1022) / (8.93*1022) = 7.12*1043 ?? this does not seem right.
