Spaceship Definition and 222 Threads

Homework Statement The position of a spaceship is: r(t)=(3+t)i +(2+ln(t))j+(7-\frac{4}{t^2+1})k and the coordinated of the space station are (6,4,9). The captian wants the spaceship to coast into the the space station. When should the engines be turned off? Homework Equations r(t)=(3+t)i...

does anyone know how to answer this problem? A spaceship ferrying workers to Moon Base I takes a straight-line path from the Earth to the moon, a distance of 384,000 km. Suppose it accelerates at an acceleration 20.6 for the first time interval 16.0 of the trip, then travels at constant speed...

This isn't really an aerospace problem, just basic physics. Been thinking about hardSF spaceship designs. Could someone comment on my logic and maths? The basic plan has a nuclear powerplant and a habitable section connected by a long tether. the whole contraption spins to provide cetrifugal...

As we know from movies such as "Star Wars" and "Star Trek", the characters move as if they were on a planet. The question is - could there be a mimic to gravity on the spaceship? Obviously, we cannot put too much mass on a spaceship, which would make the spaceship much more inert to...

Why is the Wikipedia article about Bell's spaceship "paradox" disputed at all? Link to the article This problem is ridiculously simple. The condition that the spaceships experience the same acceleration implies that their world lines will have the same shape. (The acceleration doesn't have...

A spaceship of mass m\ \text{kg} is propelled by converting r\ \text{kg} of its mass into energy every second. Assume no friction and a perfectly efficient system. 1) Find the velocity of the spaceship at time t. 2) Find its acceleration at time t. 3a) Find the distance it has traveled...

With the engines off, a spaceship is coasting at a velocity of +230 m/s through outer space. The ship carries rockets taht are mounted in firing tubes, the back ends of which are closed. It fires a rocket straight ahead at an enemy vessel. The mass of the rocket is 1300 kg, and the mass of the...

I tried using equations useing different methods of solving this problem but no cigar. If anyone can help me just to get started that would be grand. Thanks A spaceship negotiates a circular turn of radius 3890 km at a speed of 33860 km/h. (a) What is the magnitude of the...

http://s7.imagehosting.us/uploadpoint/imagehosting_upload_storage/nouser_780/T0_-1_780959.png This is the problem I am working on. I do not know how I am supposed to find the force exerted on the spaceship. I figured I would find the gravitational attraction of the asteroids on each other...

This seems like it should be very easy but I keep getting the wrong answer. Here is the problem. "Calculate the force of gravity on a spacecraft 32000 km (5 Earth radii) above the Earth's surface if its mass is 1300 kg." In my book there is problem very similar so I tried doing the same...

A spaceship ferrying workers to the moon takes a straight line path from the Earth to the moon, a distance of about 400,000 km. It accelerates at 15.0 m/s^2 for the first 10 minutes of the trip, then travels at a constant speed until the last 10 minutes when it accelerates at - 15.0 m/s^2, just...

between the moon and the Earth a Spaceship travels. A person goes on a spacewalk and pushes the tractor trailer sized vehicle. Will the person be pushed back even though things in zero gravity have no mass?

a) The acceleration of a spaceship is given by a(t) = 3 m/s2 – (2 m/s3 ) t. Find the initial velocity V0 so that the spaceship is at the same point where it started after 5 seconds. No idea how to do this one, but do you need to integrate? Ty

Lets assume I create a spaceship that is powered by vacuum energy which gives the spaceship an unlimited fuel supply. I leave Earth at full power and remain at full power forever. I have an accelerometer mounted to the dash just below the fuzzy dice. Will my accelerometer measure my ship...

How fast must a spaceship be traveling relative for one day on the spacecraft to equal 2 days on Earth? I'm pretty sure that t(0) = 172,800 seconds, and t = 86,000 seconds. Do I just need to use ∆t = t – t(0), simplify that to t = γt(0), and then since γ = 1+ (1/2)(v^2)/(c^2); take the...

Yet another "spaceship moving at .9c" thread What I'd like to see a thread about is what would happen if a spaceship, moving at .9c, were to impact a planet. Let's say the spaceship was 100,000 metric tons, roughly the size of a Nimitz-class aircraft carrier. It's not hard to figure out the...

Seen in another thread: Does this implies that a spaceship, inside a black hole, accelerating in the direction OPPOSITE to the singularity would actually accelerate TOWARDS the singularity? Or does it simply mean that no matter how fast a speed he reaches through his acceleration, he would...

Hi all, I have become frusturated at a conservation of momentum problem. A space ship(ss) with a mass of 2.0*10^6 [kg] is crusing at a speed of 5.0*10^6 [m/s], when it blows up. One section(s1), with mass 5.0*10^5 [kg] is blown straight backwards at a speed of 2.0*10^6 [m/s]. The second...

If a hypothetical aether contained positive and negative electric charges, then a "local" electric field could exist between a proton and one of the charges.If the aether also contained magnetic charges and the proton had a small magnetic charge of its own, then the proton, like a photon...

Hi, I am programming a game that involves controlling spaceships with a top-down 2d dimensional view. I want this game to have as realistic a physics model as possible. The idea is that you select a ship and then click on a destination. The ship then turns to an appropriate heading (turning...
