Does this velocity sound reasonable?

In summary, the expected range for velocities is typically between 0 to 100,000 meters per second, although this can vary depending on various factors. Velocities can be calculated using the formula v = d/t and may involve additional factors such as acceleration and forces. The accuracy of velocity measurements depends on the precision and accuracy of the measurement tools. The physical possibility of a velocity is determined by the laws of physics, and comparisons between velocities can vary depending on the specific context and type of velocity being discussed.

Homework Statement


The radius of the Earth is 6.86 e6 m and the mass of the Earth is 5.98 e24kg. There is a satellite floating in space at a point where the Earth's gravitational acceleration is 3.2 m/s^2.

What is the velocity of the satellite



Homework Equations


Possibly A cent = V^2/R
g = GM/R^2
Fg = GMm/R^2


The Attempt at a Solution


So I did 3.2 = GM/R^2...R = 1164480.51. Then I did Ac = V^2/R. And solved for V^2. I got 1930 m/s. Does this sound like a reasonable velocity for a satellite?

FAQ: Does this velocity sound reasonable?

Is this velocity within the expected range?

It depends on the context and the specific velocity in question. In general, velocities within the range of 0 to 100,000 meters per second are considered reasonable. However, this can vary depending on factors such as the object's size, mass, and environment.

How was this velocity calculated?

The velocity can be calculated using the formula v = d/t, where v represents velocity, d represents distance, and t represents time. Other factors such as acceleration and forces may also be involved in the calculation depending on the situation.

Can this velocity be measured accurately?

Accurately measuring velocity depends on the precision and accuracy of the measurement tools and techniques used. In most cases, modern technology allows for highly accurate velocity measurements. However, there may be limitations in certain circumstances.

Is this velocity physically possible?

It is important to consider the laws of physics when evaluating the physical possibility of a velocity. If the calculated velocity exceeds the speed of light or violates other physical laws, then it is not physically possible.

How does this velocity compare to other velocities?

The comparison of velocities depends on the specific context and type of velocity being discussed. For example, a velocity of 5 meters per second may be considered fast for a snail but slow for a car. Comparisons can also be made between different velocities of the same object at different times, such as before and after acceleration.
