Suppose that a tiny space invader (m=0.47 kg) and the new space station orbit Earth at the same height from Earth’s surface. Whi

Ad libitum [116K]

The tiny space invader and the new space station will have equal orbital speed.

<h3>The orbital speed of satellite </h3>

The orbital speed of satellite on Earth surface is given as;

$V = \sqrt{\frac{GM}{r} }$

where;

V is the orbital speed
G is universal gravitation
M is mass of the Earth
r is the radius of the circular path

Since the two objects are at the same height from Earth's surface, the distance from the central point (r) will be the same. Thus, the two objects will have equal orbital speed.

you push a coin across a table the coin stops how does this motion relate to balanced and unbalanced forces

-BARSIC- [3]

When you exert a force on the coin, it will accelerate. If you push the coin and it moves at a constant velocity, the friction force must be equal to the force that you are exerting. This is an example of a balanced force. When the net force is greater than 0 N, the is an unbalanced force.
