Question
What's the correct answer for c?
Transcribed Image Text:**Transcription: Satellite Orbital Dynamics**
A satellite of mass 175 kg is launched from a site on Earth's equator into an orbit at 180 km above the surface of Earth. (The mass of the Earth is \(5.98 \times 10^{24}\) kg, and the radius of the Earth is \(6.38 \times 10^3\) km.)
**(a)** Assuming a circular orbit, what is the orbital period of this satellite?
- **Answer:** 5286 s ✓
**(b)** What is the satellite's speed in its orbit?
- **Answer:** 7798 m/s ✓
**(c)** What is the minimum energy necessary to place the satellite in orbit, assuming no air friction?
- **Answer:** 6.38 ✗
*Note: Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.*
