Do you follow what has been posted so far? If not I will be glad to try to explain.

In this case, I believe the magnitude of F given should be differentiated w/r to r ...

where is a rate of change of force magnitude in and can be determined from the given info.

... The problem is poorly worded, imho. The question asking "how fast" could have been made more clear. - Nov 20th 2012, 09:26 AMMarkFLRe: Newton's Law of Gravitation
You are most likely right, as no information is given about the speed of ascent. When I hear "how fast" I think of a time rate of change.
