Question

4.If a satellite moves with constant speed in a perfectly circular orbit around the earth, what is the direction of the acceleration of the satellite? Outward away from Earth; b. The acceleration is zero because the speed is constant: c. In the forward direction_ Inward toward the Earth_ In the backward direction,

A satellite travels around Earth in uniform circular motion at an altitude of 35,822 km above Earth’s surface. The satellite is in geosynchronous orbit. In the below figure, the satellite moves counterclockwise (ABCDA). (State directions in terms of the x- and y-axes.) The radius of Earth is 6371 km. What is the magnitude of the satellite’s average acceleration for one quarter of an orbit, starting at A and ending at B? m/s2

00:01 Okay, so if you have a satellite orbiting the earth or any planet in a perfectly circular orbit, this is not a perfect circle, but let's pretend it is.
00:16 We want to know what direction the acceleration would be pointing in.
00:19 So in circular motion, the acceleration is the centripetal acceleration, and that is always pointing inward.
00:29 So at this point, you'll be pointing inward toward the earth up here, pointing inward toward the earth, wherever it's at in its orbit...
