Solving Physics Time Problem: Apollo Lunar Landing Mission

In summary, the Apollo Lunar Landing Mission took approximately 3 days to reach the moon, traveling around 238,855 miles. The timing of the mission was affected by factors such as distance, speed, and alignment. The astronauts used a device called the Apollo Lunar Surface Close-up Camera to measure and track time, which was synchronized with the mission clock on Earth. The precise timing of the mission was crucial for its success, as any errors could have resulted in missing the target or running out of fuel. The mission was launched on July 16, 1969, at 9:32 am EST and landed on the moon on July 20, 1969, at 4:17 pm EST, lasting about 8 days.

1. Homework Statement

During an Apollo lunar landing mission, the command module continued to orbit the Moon at an altitude of about 104 km. How long did it take to go around the Moon once?

2. Homework Equations

T^2=[4pi^2(r)]/g

3. The Attempt at a Solution

square root of 4pi^2(7.35e25+104000)/9.8=1.7e13min. this answer does not make sense though

Where does the 7.35e25 come from?

, as it is much longer than the actual duration of the mission

I would like to point out that the equation used in this attempt at a solution is incorrect. The equation provided, T^2=[4pi^2(r)]/g, is used for calculating the period of an object in circular motion around a central mass. However, in this scenario, the command module is not in a circular orbit around the Moon. It is in a roughly elliptical orbit, with its closest point to the Moon being 104 km and its farthest point being much farther away.

To accurately calculate the time it takes for the command module to orbit the Moon once, we would need to know the exact shape and size of its orbit. Additionally, the mass of the Moon and the gravitational constant would also need to be taken into account.

Furthermore, the given answer of 1.7e13 minutes is not a reasonable time for the command module to orbit the Moon once. As you mentioned, it is much longer than the actual duration of the mission, which was approximately 8 days.

In order to solve this problem accurately, we would need more information about the orbit of the command module and its velocity. However, based on the given information, we can estimate that it would take the command module around 90 minutes to orbit the Moon once, similar to the orbital period of the International Space Station around Earth.

In conclusion, it is important to use the correct equations and consider all relevant factors when attempting to solve physics problems. Without the necessary information, it is difficult to accurately calculate the solution.
 

1. How long did it take for the Apollo Lunar Landing Mission to reach the moon?

The Apollo Lunar Landing Mission took approximately 3 days to reach the moon. The spacecraft had to travel around 238,855 miles to reach its destination.

2. What factors affected the timing of the Apollo Lunar Landing Mission?

The timing of the Apollo Lunar Landing Mission was affected by several factors, including the distance between Earth and the moon, the speed of the spacecraft, and the alignment of the planets.

3. How did the astronauts measure and keep track of time during the Apollo Lunar Landing Mission?

The astronauts used a device called the Apollo Lunar Surface Close-up Camera (ALSCC) to measure and keep track of time during the mission. This device had a built-in timer that was synchronized with the mission clock on Earth.

4. What was the precise timing of the Apollo Lunar Landing Mission?

The Apollo Lunar Landing Mission was launched at 9:32 am EST on July 16, 1969, and the lunar module landed on the moon at 4:17 pm EST on July 20, 1969. The entire mission lasted about 8 days.

5. How did the precise timing of the Apollo Lunar Landing Mission affect the success of the mission?

The precise timing of the Apollo Lunar Landing Mission was crucial for its success. Any errors in timing could have resulted in the spacecraft missing its intended target or running out of fuel. The astronauts also had to time their activities carefully to ensure they completed their tasks within the designated time frame.
