pls help i nees help

Answer 1

Answer:

1.The velocity of the spacecraft at position 2 is greater than the velocity of the craft at position 4.

This is due the gravity field of the planet (The Earth in this case) is used to accelerate the craft. This is true when in a specific point the direction of the movement of the craft is the same direction of the movement of the planet.

2. At position 1, the direction of the spacecraft changes because of the gravitational force between Earth and the spacecraft.

This is the exact and correct point where the trajectory of the spacecraft enters into a circular orbit because of the attraction due gravity of the Earth and therefore changes its direction.

3. Position 3 represents the orbital path or velocity of Earth

Being this the orbital path of the Earth and considering the trajectory of the craft, the condition of accelerating the craft is accomplished.
