At what point in an elliptical orbit is the acceleration maximum? At what point is it minimum? Justify your answers.
A spaceship travels in a circular orbit around a planet. It applies a sudden thrust and increases its speed by a factor f. If the goal is to change the orbit from a circle to a parabola, what should f be if the thrust points in the tangential direction? Is your answer any different if the thrust points in some other direction? What is the distance of closest approach if the thrust points in the radial direction?
The Earth spins at 460 meters per second at the equator. The radius of the Earth is 6.37 x 106 m. A person who believes in a flat Earth says that if the Earth was round and spinning that fast we would all fly off. Imagine if you were standing inside a hollow earth. How much centripetal acceleration would you experience? How does this compare to the acceleration due to gravity we feel at the Earth’s surface? Does it explain why we don’t fly off the Earth due to the spin?
