What are two possible paths of a spacecraft that just launched from earth but that is not traveling orbital velocity?

The spacecraft will follow an elliptical orbit with one focus at the Earth's centre, which approximates a parabola, before it hits the surface again.

Why are rockets launched as close to the equator as possible?
Rockets are launched as close to the equator as possible to launch satellites most economically by taking full advantage of the Earth's rotational velocity, which is about 1000 miles per hour at the equator and slower at all higher latitudes. This is 1000 miles per hour less speed that the rocket needs to provide and a significant savings in rocket fuel. However, other rockets are not launched from the equator as there is no similar advantage (e.g. rockets launching polar orbiting satellites or military warheads can be launched from anyplace and going to the equator to launch them would be an unnecessary expense with many disadvantages).
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Is it possible to travel at a negitave speed?
Negative speed isn't possible, but negative velocity is.
Is it possible of a body to have its velocity and acceleration pointing in opposite direction plot a velocity-time graph if yes?
Yes, it is possible. For example, if you through an object up, its velocity would initially be in the "up" direction, but its acceleration would be in the "down" direction.
An object experiences a net zero external unbalanced force is it possible for the object to be travelling with a non-zero velocity?
what a stupid qn. ya it is possible
Why does the space station travel so fast?
The International Space Station is in a low Earth orbit between 199 mi and 216 mi. To maintain this orbit, the space station has to travel at a speed of about 17,500 miles per hour. If a spacecraft was launched sideways off the Earth with a low velocity, gravity would pull it towards the ground. If the spacecraft was launched at a faster velocity, it would hit the ground at a farther distance because the ground would be curving away at a faster rate. However if the spacecraft was launched fast enough, the Earth would constantly curve away as the spacecraft falls indefinitely. The spacecraft would be in orbit. The speed required for the International Space Station to orbit is 17,500 miles per hour. The higher an object's orbit is, the slower it has to travel to maintain that orbit.
Can an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Two rockets are traveling at exactly the same speedhow is it possible that one rocket can be traveling at an orbital velocity while the other rocket is traveling at an escape velocity?
the rocket is just gonna explode in clear view like the bumuda triangle leaves no marks of the murders
How is the speed of a spacecraft measured?
Velocity is reported in knots
How do spacecraft take off from earth?
They need to reach escape velocity (about seven miles per second) to break away from Earth's gravity. (Anything traveling more slowly will eventually fall back to Earth.)
Compare velocity from acceleration?
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
How do you travel unto space?
You need a spacecraft that will exceed escape velocity.
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?
When something is traveling at a constant velocity it has no acceleration. In other words your answer is 0.
What is the acceleration of a ball that is traveling at a constant velocity of fifty miles and has been traveling for over 2 minutes?
If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
Is it possible in straight line motion a particle have zero and non-zero velocity explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
How are slingshot mechanisms used to accelerate interplanetary spacecraft?
Good question. Imagine a spacecraft is approaching a planet. The planet is moving around the sun. The spacecraft path is adjusted to approach the trailing limb of the planet -- the rear edge of the planet when you look at its orbit around the sun, not its dark side. The planet pulls on the spacecraft as it goes by (and actually the spacecraft pulls on the planet, too). If the spacecraft were close enough to the planet, and traveling slowly enough, it would be captured by the planet. But it is possible to put the space craft in a path so that will not be captured--it can be pulled by the planet so that the spacecraft gains velocity. The planet loses velocity, but since planets are huge and spacecraft small, the planet's velocity is barely affected. It is hard to visualize this, but imagine a ping pong ball being struck by a soccerball in mid-air (this would make a good science class demonstration)--the ping pong ball will pick up tremendous speed by being struck by a heavier ball. The heavy ball will hardly notice it. You can do this by dropping the soccer ball with the ping pong ball on top of it. Slingshotting a spacecraft (also called gravity assist) works in a similar way except the spacecraft would be pulled by the planet's gravity instead of being pushed (as with the two-ball demonstration).
