A piece of space debris is travelling in an elliptical orbit
around a planet. At its closest point to the planet, the
debris is travelling at 5000ms. When the debris is
10000km from the planet, it travels at 5000kmhr. How
close does the debris get to the planet in its orbit?
If a 5-kg stone is orbiting at 4 m/s in circular motion with the diameter of 5.6 m. What is the magnitude centripetal acceleration?
