Space Shutte Centripetal force problem

In summary, to calculate the speed of the space shuttle when releasing a satellite into a circular orbit 555km above the earth, the equation V= square root ((GM)/r) is used. However, since the mass was not given, the force of gravity cannot be calculated and additional information is needed. The radius of the earth is necessary, which can be looked up as 6000km. From this, GM can be calculated using g. The given r value of 555000km is not accurate as it does not include the radius of the earth.

Homework Statement



The space shuttle releases a satellite into a circular orbit 555km above the earth
how fast must the shuttle be moving when release occurs in m/s?

Homework Equations



V= square root ((GM)/r)
r= 555000
G= 6.67 * 10^-11
-mass was not given so I am not sure how to plug it in
-I got that equation but making force of gravity proportional to centripetal force

How about you show what you did? That will help to see where you went wrong.

Welcome to PF, mayla1190! :smile:

You do need some extra information to solve this problem.
I think you need the radius of the earth, but you can look this up (6000 km).
From this you can also calculate GM (using g).

Btw, your r is not quite right, since you've neglected to include the radius of the earth.
 

Related to Space Shutte Centripetal force problem

1. What is centripetal force and how does it apply to space shuttles?

Centripetal force is the force that keeps an object moving in a circular path. In the case of space shuttles, this force is provided by the gravitational pull of the Earth, which keeps the shuttle in orbit.

2. How is the centripetal force calculated for space shuttles?

The centripetal force for a space shuttle is calculated using the formula F = mv²/r, where m is the mass of the shuttle, v is its velocity, and r is the radius of its orbit.

3. What factors affect the centripetal force of a space shuttle?

The centripetal force of a space shuttle is affected by its mass, velocity, and the radius of its orbit. Other factors such as atmospheric drag and gravitational pull from other celestial bodies can also have an impact.

4. How does centripetal force impact the stability and maneuverability of a space shuttle?

Centripetal force plays a crucial role in maintaining the stability and maneuverability of a space shuttle in orbit. It keeps the shuttle in a circular path and allows it to maintain a constant velocity. Without this force, the shuttle would continue in a straight line and eventually drift away from its intended orbit.

5. Are there any risks associated with centripetal force in space shuttles?

While centripetal force is essential for keeping a space shuttle in orbit, it can also pose some risks. If the force is too strong, it can cause structural damage to the shuttle, and if it is too weak, the shuttle may lose stability and fall out of orbit. Additionally, the high speeds and forces involved in spaceflight can also have adverse effects on astronauts' bodies.
