Hello, I just took the test and your answer would be. The mechanical energy isn't conserved. Some energy is lost to friction.

Paraphin [41]
ANY closed orbit exists because of the centripetal force of gravity.
Without the force of gravity, the satellite would simply sail away
in a straight line.

The orbit you're describing happens to be a circular orbit, but it
doesn't have to be circular.

In order to slide a heavy desk across the floor at constant speed in a straight line, you have to exert a horizontal force of 80
notka56 [123]
The hint is "constant speed". 
If there is a net force on an object, what occurs to that object? F net = m*a.... It accelerates! 
So, if the desk is going at a CONSTANT speed, what does that tell you about the acceleration? There is a change in speed. 
Fnet = m*a Since a = 0 Fnet = 0 
Fnet = sum of the force... reflect the direction of F as the positive direction. Sum of the forces in the direction of F = 0 0 = F - friction F = friction 
So, if F = 800 N, then friction = 800 N in the opposite direction.

mamaluj [8]

I believe it's a floating balloon because for every action there is an equal and opposite reaction, so the balloon floats up and eventually floats back down.
