Earth radius is 6371 km ... google
orbit radius ... 6371 + 616
circumference ... 2 π r
(a) speed = circumference / period
(b) a = speed^2 / r
An Earth satellite moves in a circular orbit 616 km above the Earth's surface. The period of the motion is 96.8min.
(a) What is the speed of the satellite?
(b) What is the magnitude of the centripetal acceleration of the satellite

the distance around once is 2PI*(radEarth+6.16e8m)
velocity then= distance/period
make certain distance is in meters, and period is in seconds.
b. what is v^2/r ?
velocity then= distance/period
make certain distance is in meters, and period is in seconds.
b. what is v^2/r ?
very helpful information. I need a teacher like you.
