To find the initial speed of spaceship one, we need to apply the principle of conservation of momentum. Since the two spaceships have equal masses, their momenta will be equal and opposite. The momentum of spaceship two is given by 150 kg * V2, where V2 is the initial speed of spaceship two. The momentum of spaceship one is given by 150 kg * V1, where V1 is the initial speed of spaceship one. Since they have equal magnitudes, we have 150 kg * V1 = 900 kg * (-V2). Solving for V1 gives V1 = - 6 V2. Since we want the initial speed in magnitude, the initial speed of spaceship one is 6 times the initial speed of spaceship two in magnitude.
The momentum of each spaceship is given by mass x velocity. Therefore, spaceship 1 has a momentum of 0 kgm/s and spaceship 2 has a momentum of 2000 kgm/s. When combined, the total momentum would be 2000 kg*m/s.
3 m/s
The initial speed of spaceship 1 can be calculated using the formula: momentum = mass x velocity. Given that the initial momentum of spaceship 1 is 9000 kgm/s and the mass is 300 kg, the initial speed can be calculated by dividing the momentum by the mass: 9000 kgm/s / 300 kg = 30 m/s. So, the initial speed of spaceship 1 is 30 m/s.
2 m/s
It will appear to slow to outside observers. That is, a twin going on a spaceship near the speed of the light will return to earth younger than his twin.
3 m/s
2 m/sec in the direction of travel of Spaceship 2, assuming they are both in frictionless outer space.
No, it is not possible to determine the speed of someone in space based on the information given. To calculate speed, we need to know the distance traveled and the time it took to travel that distance, and in this case, we don't have either of those values. We know that one year on the spaceship is equal to 50000 years on Earth, but that does not provide us with any information about the speed of the spaceship.
Momentum = mass x speedSince Spaceship-#1 is not moving, it has no momentum. Their combined momentumis that of Spaceship-#2 alone.Momentum = mass x speed = 200 x 10 = 2,000 kilogram-meters per second.
2,000 kg-m/s
The initial speed of spaceship 1 can be calculated using the formula: initial momentum = mass * velocity. Therefore, the initial speed of spaceship 1 would be 6 m/s.
