A 200 pound astronaut and equipment move with a velocity of 2msec toward an orbiting spacecraft How long will the astronaut need to fire 100 N rochet to stop the motion relative to the spacecraft?

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)

When an astronaut lands on the moon what is his mass?
His mass does not change, only his relative weight.
What is Speed of New Horizons spacecraft?
After its last engine shutdown, New Horizons was moving at 10.10 miles per second (36,373 mph) relative to the Earth.
What is mercurys rotation rate?
Its very slow, despite orbiting the sun in a very quick time. it rotates once every 58.6 days relative to background stars.
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.
What keeps the moon orbiting around the earth?
Orbits are established by the combined effects of gravitational attraction and relative velocity. In other words, the moon, like any orbiting body, moves forward (tangent to its orbit) at a speed just sufficient to ensure that as it falls toward the earth due to gravity, it has moved far enough that the two motions combine to keep it at a roughly stable distance from the earth.
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.
When an astronaut lands on the moon what is his mass?
His mass does not change, only his relative weight.
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.
If a spacecraft is approaching the earth relative to the radio signals it send out the signal received on the earth have?
Shorter wavelength, higher frequency.
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
What is the best humidity level for electronic equipment?
40% to 60% relative humidty
What is the number of satillites on Saturn?
Venus is unique in that it and Mercury are the only planets in the solar system with no natural satellites. Currently the European Space Agency (ESA) has a satellite named Venus Express orbiting the planet.
What does the acronym OEE stand for relative to manufacturing performance measurement?
Operating Equipment Effectivity

What is mercurys rotation rate?
Its very slow, despite orbiting the sun in a very quick time. it rotates once every 58.6 days relative to background stars.
What is the definition of apparent relative orbit with respect to binary stars?
A binary star is a star system consisting of two stars orbiting around their common centre of mass
