Question: The "escape velocity" of something is the minimum speed it must reach to never return due to gravity. In other words, it's the lowest speed that can theoretically get an object infinitely far away.What is the escape velocity from the ...
The second question (b) asks about the height the elevator needs to have in order for an object released from it to ultimately escape Earth's gravitational influence. The third question (c) is similar to the first, but asks for the minimum initial speed needed for an object ...

Escape velocity is simply the speed of an object that's …uh, let's say, shot out of a cannon, theminimuminitial speed so that the object could later escape Earth’s gravity on its own. 逃逸速度仅仅是物体的速度,额…比如说,将一个大炮射出用最小的起始速度,这个物体随后可以凭它自己摆脱地球...
