- Assume that we have a distant Star-Planet system with no other planets and the Star is the same as the Sun and the planet is the same as the Earth. This is called an "Earth analog system or "Earth twin". The masses and the orbits are the same except you can assume a perfectly circular orbit. A) Calculate the equation for the orbital velocity of a planet on a circular orbit. To do this use the equation for average speed: distance=rate x time. In a circular orbit, the speed is always the same, so you can use a time that is one full orbital period (1 year). What is the distance that a planet on a circular orbit travels in this time? Calculate the speed of the Earth twin in meters/second. Mass of the sun: 2 x 1030 kg. Mass of the Earth: 5.97 x 1024kg (Note: I think I understand how to use the distance= rate x time, but I'm not sure what to input for rate in this situation. I am also not sure how to calculate the speed of the Earth twin)A geosynchronous Earth satellite is one that has an orbital period of precisely 1 day. Such orbits are useful for communication and weather observation because the satellite remains above the same point on Earth (provided it orbits in the equatorial plane in the same direction as Earth’s rotation). Calculate the radius of such an orbit based on the data for Earth in Appendix D.An artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 9.065 m/s2. Determine the orbital period of the satellite? Your answer should be a unit of time.
- A 5 kg mass is spun around in a circle of radius 2m with a period of 7 s. What equation would you use to calculate the centripetal acceleration? Calculate the centripetal acceleration. Possible Formulas that can be used to answer the question: v=(2πr)/T ac=v2/r ac=(4π2r)/T2 Fc=mac Fg=mg F=(Gm1m2)/d2 g=Gm/r2 T2=(4π2/Gm)r3 v=√(Gm)/r g=9.80m/s2 G=6.67x10-11 (N∙m2)/kg2A satellite orbits the Earth at a radius of 2.2×10 7 m. What is its orbital period?An astronaut orbiting the Earth is preparing to dock with a Westar VI satellite. The satellite is a circular orbit 500 km above the Earth's surface, where the free-fall acceleration is 8.11 m/s2. Take the radius of the Earth as 6400 km. Determine the speed of the satellite. m/s Determine the time interval required to complete one orbit around the Earth, which is the period of the satellite. min
