What is Spaceship: Definition and 213 Discussions

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...
