An astronaut leaves a spaceship that is moving through free space. Will the spaceship move off and leave the astronaut behind?

Physics

When an astronaut leaves a spaceship that is moving through free space, the spaceship does not move off and leave the astronaut behind.

This is because when the astronaut is inside the spaceship, which is moving in free space, the astronaut also has the same velocity as the spaceship. Hence, when he leaves the spaceship, there is no relative velocity between the spaceship and the astronaut. This is the reason why the spaceship will not move off and leave the astronaut behind.

A spaceship or a spacecraft is an especially designed vehicle that is used to travel to outer space. It can be used for space exploration, transportation of humans and cargo, and meteorological purposes.

An astronaut is a person who has undergone specific training to travel to space. The duties of an astronaut aboard a spaceship can vary. Usually, a pilot and a commander work together to lead the mission. Other positions could be science pilot, mission expert, payload commander, and flight engineer.

In what order does light pass through structures of the eye? lens, cornea, retina cornea, pupil, lens pupil, iris, lens pupil, c
Mrrafil [7]

Answer: Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.

Explanation:

When light rays reflect off an object and enter the eyes through the cornea (the transparent outer covering of the eye), you can then see that object. The cornea bends, or refracts, the rays that pass through the round hole of the pupil.

A space vehicle is traveling at 5425 km/h relative to the Earth when the exhausted rocket motor (mass 4m) is disengaged and sent
lana66690 [7]

Answer:

V_{cE}=1489m/s

Explanation:

Given data

Space vehicle speed=5425 km/h relative to earth

The rocket motor speed=81 km/h  and mass 4m

The command has mass m

From the conservation of momentum as the system isolated

p_{i}=p_{f}\\

Since the motion in on direction we can drop the unit vector direction

MV_{i}=4mV_{mE}+mV_{CE}

Where M is the mass of space vehicle which equals to sum of the motors mass and command mass.

The velocity of the motor relative to the earth equals the velocity of the motor relative to command plus the velocity of the command relative to earth

V_{mE}=V_{mc}+V_{cE}

Where Vmc is the velocity of motor relative to command

This yields

5mV_{i}=4m(V_{mc}+V_{cE})+mV_{cE}\\5V_{i}=4V_{mc}+5V_{cE}

Substitute the given values

V_{cE}=\frac{5V_{i}-4V_{mc}}{5}\\ V_{cE}=5425*\frac{1000}{60*60}(m/s)-\frac{4}{5}*81\frac{1000}{60*60}(m/s)\\  V_{cE}=1489m/s
