Scientists want to place a 3300 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 2.2 times the radius of Mars above the surface of the planet. Here is some information that will help solve this problem:
mmars = 6.4191 x 1023 kg
rmars = 3.397 x 106 m
G = 6.67428 x 10-11 N-m2/kg2
1) What is the force of attraction between Mars and the satellite?
Well, if I were the satellite, I would definitely be attracted to the Red Planet. But let's calculate the actual force of attraction between them.
To find the force of attraction between Mars and the satellite, we can use Newton's law of universal gravitation. The formula is F = (G * m1 * m2) / r^2, where F is the force of attraction, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.
In this case, the mass of Mars (mmars) is 6.4191 x 1023 kg, the mass of the satellite is 3300 kg, and the distance between them is the sum of the radius of Mars (rmars) and 2.2 times the radius.
Let's plug in the values and calculate the force of attraction:
F = (G * mmars * msatellite) / (rmars + 2.2 * rmars)^2
F = (6.67428 x 10^-11 * 6.4191 x 10^23 * 3300) / (3.397 x 10^6 + 2.2 * 3.397 x 10^6)^2
Now, I could spend hours crunching those numbers, but I have to attend my clown academy class soon. So, let me just grab my calculator...

Oops! Seems like I dropped my calculator. Maybe I'm not cut out for serious math.
But fear not! To get the approximate force, you can always consult an actual calculator or use a simulation tool to make your life easier.
To find the force of attraction between Mars and the satellite, we can use Newton's Law of Universal Gravitation. The formula is:
F = (G * mmars * msatellite) / r^2
Where:
F is the force of attraction between Mars and the satellite
G is the gravitational constant (6.67428 x 10^-11 N-m^2/kg^2)
mmars is the mass of Mars (6.4191 x 10^23 kg)
msatellite is the mass of the satellite (3300 kg)
r is the distance between the center of Mars and the satellite (2.2 times the radius of Mars)
Let's plug in the values:
r = 2.2 * rmars
F = (G * mmars * msatellite) / (2.2 * rmars)^2
Now, let's substitute the given values:
mmars = 6.4191 x 10^23 kg
msatellite = 3300 kg
rmars = 3.397 x 10^6 m
G = 6.67428 x 10^-11 N-m^2/kg^2
Calculating:
r = 2.2 * 3.397 x 10^6 m
r = 7.4734 x 10^6 m
F = (6.67428 x 10^-11 N-m^2/kg^2 * 6.4191 x 10^23 kg * 3300 kg) / (7.4734 x 10^6 m)^2
Solving this equation will give us the force of attraction between Mars and the satellite.
To find the force of attraction between Mars and the satellite, you can use Newton's law of universal gravitation. The formula for this law is:
F = (G * m1 * m2) / r^2
where F is the force of attraction, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the two objects.
In this case, the mass of Mars (mmars) is given as 6.4191 x 10^23 kg, the mass of the satellite is given as 3300 kg, and the distance between Mars and the satellite is 2.2 times the radius of Mars (rmars).
To solve the problem, you need to calculate the force of attraction. Here are the steps:
1. Calculate the distance between Mars and the satellite:
- Multiply the radius of Mars (rmars) by 2.2 to get the distance above the surface of the planet.
2. Calculate the force of attraction:
- Substitute the values into the formula: F = (G * mmars * msatellite) / r^2
- Substitute the values for G, mmars, msatellite, and r that you have calculated in step 1.
- Calculate the force using a calculator.
The result will give you the force of attraction between Mars and the satellite.
F = G M1 M2 / d^2
d = 2.2+1 = 3.2 mars radius=10.9*10^6 meters
= 6.67*10^-11 (3300)(6.42*10^23)10^-12/(10.9)^2
= 1194 * 10^0
= 1194 Newtons
