Looks like you've just misread the question. 0.34 seconds isn't how long it takes the pole vaulter to fall onto the pad, it's how long it takes the pad to "pop back" after the vaulter lands. So your first step should be to figure out how long it takes him to reach the pad. The 0.34 seconds don't...
A simple phrasing of Newton's first law is "Objects will not change velocity unless acted upon by a force". Velocity is relative to your frame of reference.
Suppose you have a brick just floating there in space, light years from the nearest gravity well, for all intents and purposes...
Sorry, I neglected to clarify that in the 2- or 3-D version of the problem. Yes, the rates of acceleration and deceleration are one and the same.
I might not be following, but you seem to have misread my rambling and poorly-summarized problem statement. Your velocity at any time until the...
Hey, all. A few days ago, I posted a poorly-worded kinematics problem, at https://www.physicsforums.com/showthread.php?p=1195234#post1195234.
I received a helpful answer practically within minutes, and shortly thereafter realized the answer was irrelevant, and that the fault lay in my...
'preciated. I really should have just taken a few minutes to look around, but I was in too much of a rush to do more than run a quick search and see whether or not my sort of question had already been posted.
On it. Or at least, plan to be on it shortly. Busy night. Thanks for the tip.
Not actually homework, but almost definitely not graduate-level stuff. No clue how to use LaTeX, so I'll have to give variables nonstandard names to make this legible.
Homework Statement
An object (say, a spaceship, or something. Something that can accelerate/decelerate at a constant...
