The force needed to keep the space shuttle moving at constant speed is 0.
The given parameters;
- <em>weight of the space shuttle, F = 750,000 N</em>
- <em>constant speed of the space shuttle, v = 28,000 km/h</em>
The mass of the space shuttle is calculated as follows;

The force needed to keep the space shuttle moving at constant speed is calculated as follows;


where;
a is the acceleration of the space shuttle
At a constant speed, acceleration is zero.
F = 76,530.61 x 0
F = 0
Thus, the force needed to keep the space shuttle moving at constant speed is 0.

Explanation:
Derived quantities are quantities dependent on fundamental quantities while derived units are the units of these quantities
Just like any other speed, it's
(total distance) / (time to cover the distance).
So you need to look up Mercury's distance from the sun, calculate the length of it's orbit, and divide that by the time it takes to go around the orbit once.
Good luck.
Answer:
Particles in solids are always vibrating (moving back and forth) in place. The vibrational motion of particles in solids is kinetic energy. Heat makes the particles in a solid vibrate faster, giving them more kinetic energy. Faster-vibrating particles bump into one another more often and hit each other harder.
