An exotic planet Vogsphere is known to have a mass that is 1/81 that of the Earth and a radius 0.25 that of the Earth. Astrophysicist Trillian built a rocket and decided to leave the planet and never to return. Given that the escape speed from the Earth is 11.2 km/s, with what speed must Trillian achieve his goal?
A BMX biker wanted to impress his family by catching some air( aka leaving the ground) while riding over a hill in Tennesse with a radius of curvature of 7.6m. If the BMX biker rides over the hill at 11.2 m/s, will she catch some air and excitee her family?
B) What is the minimum speed the biker has to travel in order to leave the ground when cresting the hill?
This is a proportional reasoning calculation. You will want to set up equations, but mostly to look at how the orbital distance affects the orbital velocity, or to set up a ratio. (Once you know how it changes you'll have to multiply by the value at the surface to get an answer in m/s.)
At the surface of the exoplanet G 9-40 b, the orbital velocity would be 1.21E+4 m/s.
What would the orbital velocity be 11 radii above the surface?
m/s.
Note: If your answer requires scientific notation, remember that OWL uses "e" notation: 1.1 x 105 is 1.1e5 to OWL.

The program is based on Kepler's laws of planetary motion as derived in Chapter 2. References to the relevant equations are given in the comment sections of the code. The user is asked to enter the mass of the parent star (in solar masses), the semimajor axis of the orbit (in AU), and the eccentricity of the orbit. The user is also asked to enter the number of time steps desired for the calculation (perhaps 1000 to 100,000) and the frequency with which the time steps are to be printed to the output file (0rbit.txt). If 1000 time steps are specified with a frequency of 10, then 100 evenly spaced (in time) time steps will be printed. The output file can be imported directly into a graphics or spreadsheet program in order to generate a graph of the orbit. Note…arrow_forward
