you did give us more to work with here than 99% of people asking for help. so gold star for you!

I know this shit has to have a pretty insane acceleration rate. it takes 1 second for the owl to move from the ground to the same level as the light source, at which point the x position of the shadow approaches infinity. So <span class="math">72\frac{m}{s^2}[/spoiler] definitely is not right.

thanks bruh i'm putting that on my resume

[Anonymous No.5532045]

I checked until you got 160m/s in the light green, and its correct. 72 seems realistic too.

[Anonymous No.5532050]

I'm not necessarily looking for the actual answer, either. If anyone has ideas on how best to think about answering the problem that would be great, too.

Also, fuck feet - used meters, and fuck positive/negative directions, didn't make negatives since it doesn't realistically matter here.

finished checking, and it seems correct.

[Anonymous No.5532059]

That seems right to you? The reason why I doubt it is correct is because <span class="math">72\frac{m}{s^2}\cdot1s = 72\frac{m}{s}[/spoiler]... after one second that bird should be flying infinitly fast shouldn't it?

*that shadow should be moving infinitly fast

[Anonymous No.5532069]

>>5532055
That seems right to you? The reason why I doubt it is correct is because 72ms21s=72sm... lets say if the owl was moving up from the ground, after one second that shadow should be moving infinitly fast shouldn't it?

Oh shit, just realized I left out a bunch of my work on the second differential. Ah well, doesn't matter too much since the answer looks wrong anyway.

that 72 is changing the whole time, leave the y value in the answer (don't insert y = 15 while you work) and you should get something of the form 360/(20-y) m/s^2 which as y gets near 20 will make the shadow go infinitely fast as 360/0 ~ infinity, but at y = 15 gives 360/5 = 72.

You are my hero. You may have sex with me any time you want to.
So I calculated instantaneous acceleration. I was thinking that there must be an "acceleration of the acceleration", but I've never actually had any scenarios where I actually dealt with that.

Looking back at the equations now it all seems so stupidly obvious.
