The satellite s travels around the earth in a circular path with a constant speed of 20 mm> h. if the acceleration is 2.5 m> s2, determine the altitude h. assume the earth's diameter to be 12 713 km.

The altitude of planet = 5989.198 km

Explanation:

    We know that centripetal acceleration, , where v is the velocity and r is the radius. In this case both acceleration and velocity is given, so we can find radius of satellite.

    v =

    a =

 So,  

 We have diameter of earth = 12713 km

        Radius of earth = 12713/2 = 6356.5 km

   The altitude of planet = Radius of planet - radius of earth

                                         = 12345.698 - 6356.5

                                         = 5989.198 km

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
