If the man and his equipment weigh 200 pounds on the earth's surface,
then their mass is 90.719 kg. (rounded)
The acceleration of the package due to a net force of 100N is [ A = F/m ] = 100/90.719 = 1.102 m/s2. (rounded)
With this acceleration applied in the direction opposite to his initial velocity,
it takes [ V/A ] = 1.814 seconds to stop. (rounded)

Why does astronauts appear weightless in their earth orbiting space craft?
Astronauts appear weightless in their Earth-orbiting spacecraft because both the spacecraft and the astronauts are in a state of free fall towards Earth. While the spacecraft is moving forward at a high velocity, it is also falling towards the planet due to gravity. This continuous free fall creates a condition known as microgravity, where the effects of gravity are still present but are not felt by the astronauts, making them seem weightless relative to their surroundings.
Why do astronauts float when in a orbiting space ship?
Astronauts float in an orbiting spaceship because both the spacecraft and the astronauts are in a state of free fall towards Earth. While the ship is constantly falling due to gravity, it also has a forward velocity that keeps it in orbit, creating a sensation of weightlessness. This condition is often referred to as microgravity, where the effects of gravity are still present but not felt in the same way as on the Earth's surface. As a result, astronauts appear to float relative to the spacecraft.
When an astronaut lands on the moon what is his mass?
His mass does not change, only his relative weight.
What is the max speed of a manned spacecraft?
The maximum speed reached by a manned spacecraft was during the Apollo 10 mission in 1969, when the spacecraft reached a speed of about 24,791 mph (39,897 km/h) relative to Earth. This speed was necessary to escape Earth's gravity and travel to the Moon.
What does TARDIS stand for?
Tardis (Time And Relative Dimension In Space) Is A Blue Police Telephone Box Which Can Travel Through Time And Space. It is used in the Sci-fi TV series 'Doctor Who'. It is both a time machine and a spacecraft.
An astronaut leaves a spaceship that is moving through free space to adjust an antenna Will the spaceship leave the astronaut behind?
No because the astronaut's relative velocity will be approximately the same as that of the spacecraft.
What is the relative speed of the spacecraft according to astronaut when He traveled for 8 years and according to earth observer is 10 years?
The difference in time experienced by the astronaut and the Earth observer is a result of time dilation, a concept from Einstein's theory of relativity. If the astronaut experiences 8 years while the Earth observer measures 10 years, the spacecraft is traveling at a significant fraction of the speed of light. The relative speed can be calculated using the time dilation formula, which reveals that the astronaut's frame of reference moves more slowly compared to that of the Earth observer. This discrepancy highlights the effects of relativistic speeds on time perception for observers in different frames of reference.

What are pros and cons of orbiting spacecraft?
Pros of orbiting spacecraft include the ability to conduct long-term observations of Earth and other celestial bodies, collect valuable scientific data, and facilitate communication and navigation services. They can also maintain a stable position relative to the planet, allowing for continuous monitoring. However, cons include high costs of development and launch, potential space debris risks, and the challenges of maintaining and servicing spacecraft over time. Additionally, they can be affected by adverse space weather and must contend with limited lifespans.
When an astronaut lands on the moon what is his mass?
His mass does not change, only his relative weight.
What keeps Apollo 8 orbiting the moon?
Apollo 8 is not orbiting the moon - it completed 10 lunar orbits during its mission in December 1968. The spacecraft's velocity and direction are precisely calculated and adjusted with thruster burns to maintain its trajectory around the moon.
What is the curved path In which a planet satellites or spacecraft revolves around another body?
The curved path in which a planet, satellite, or spacecraft revolves around another body is called an orbit. Orbits can be circular or elliptical in shape, depending on the gravitational forces at play and the relative velocities of the objects involved. The gravitational attraction between the two bodies keeps the orbiting object in its path, balancing the inertia of its motion.
Does the universe move while the planets are orbiting?
Yes, everything is moving relative to everything else.
How does the speed of a spacecraft affect its orbit?
It stabilizes or de-stabilizes it. A spacecraft needs to maintain a relative velocity of 25,000 miles per hour in order to counteract the earth's gravitational pull on the spacecraft. At a lesser speed, the craft will start to fall back to earth.
What is the changing apperances of the moon from the earth?
They are called phases of the moon. They are caused by the moon orbiting the earth and changing its relative angle to the sun
