Two satellitess, and S, orbit around a planet P in circular orbits of radil r, - 5.15 x 106 m, and r,- 8.40 x 10 m respectively. If the speed of the first satellite S, is 1.65 x 10 m/s, what is the speed of the second satellite S,?

A moon travels around an unknown planet. If the period of the orbit is 1 day, and the radius of the orbit is 1.37 x 10^7 m, what is its speed in m/s?

Earth orbits our Sun counter-clockwise at average speed 29 786 m/ . Moon orbits Earth ccw at average distance 384.4 Mm in 2 360 592 s. What is our Moon's average speed around Earth?

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 planet has a moon which is 2.5x10^9 m  away from the planet, the moon makes a circular orbit around the planet with a period of 18 days, what is the centripetal acceleration in m/s^2 of the moon?

Algebraic relation. Two particles, A and B, are in uniform circular motion about a common center. The acceleration of particle A is k times that of particle B and the speed of A is 3 times that of B. Find the numerical value of the ratio of their radii, A/B if [] k 9.4 B = 1.4 TA/TB = Please record your numerical answer below, assuming three significant figures.

Comets travel around the sun in elliptical orbits with targe eccentricity. If a comet hos speed 2.2 × 10ª m/s when is at a distance of 2.5 x 10" m from the center of the sun, what is its speed when ot a distance 5.5 x10"m?

Suppose an object is traveling in a circle of radius 10 m. if the object has a period of 6 s, what is its orbital speed (in m/s)?

(a) The speed of the Earth in its orbit around the sun can be calculated by dividing the circumference of theEarth’s orbit by the number of seconds in a year. The result isv= 29,870 m/s. What is the centripetalforce due to the Sun experienced by the  Earth?

If an airplane is flying at 140 miles per hour east and turns in a smooth curve with a diameter of 3 miles, what is its centripetal acceleration in m/s2 ?  SYW!!!
