Why must a horizontally moving projectile have a large speed to become an earth's satellite?
At lower speed, the object will fall back on the ground.
Since, earth is curved, if the object has enought speed, the object can try to fall beyond the curvature of the earth.
Thus, it will not hit ground at all.
The speed to achieve it is around 8 km/s.
If the object is faster than 11.4 km/s then the object will never return.
It is called escape velocity.

What type of satellite orbits perpendicular to the earths equator?
polar satallite
Why is a polar orbit useful for surveying purposes?
it carries the the satellite over the earths north and south poles
What is the inclination of a satellite to the earths equator?
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.

When in orbit a satellite such as the space shuttle is either a projectile or a non-accelerated motion or free from earths gravity or an ellipse?
A satellite like the space shuttle is in a state of freefall, which means that it is continuously accelerating towards Earth due to gravity, but its forward velocity keeps it in orbit, creating an elliptical path around the planet. This motion can be described as a projectile in a non-accelerated or constant velocity state within the orbital path.
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
Why is it important that the projectile in the last question be above the Earths atmosphere?
because of Air Ressistant
