I notice that I plugged in 14º and not 40º for the ramp angle right off the bat, but the answer would still be incorrect.

Homework Statement A skateboarder in a death-defying stunt decides to launch herself from a ramp on a hill. The skateboarder leaves the ramp at a height of 1.4 m above the slope, traveling 15 m/s and at an angle of 40° to the horizontal. The slope is inclined at 45° to the horizontal. With what...

Wow, cannot believe I did that. That was the problem - answer accepted. Thanks for all your help!

Also, I did not include this work on the above screenshot, but I also did it with the "old" equation r = cube root ((T2Gm)/(4pi2)) and got the same result - 39743 m. What am I doing wrong? I must have the wrong understanding of the entire problem. I do not understand how the Planet Endor is...

I tried again with consistent rounding to 2 decimal places and followed a different method getting there, still the incorrect answer:

Does that mean the planet is meaningless towards solving the problem? If you can Ok, I see how those numbers adjusted to significant figures would have a pretty significant impact on the result. I will try again, making sure I'm consistent with rounding and sig figs, and find just the center to...

I really do not think the answer was denied due to a rounding error. I have done 30+ assignments on this platform and getting the right answer, but not submitting it with the correct number of sig figs has never been an issue. I am looking for a review of my work/formulas...is how I solved for...

That is possible, but before my first submission it said "tolerances for answers are quite large" - plus, since data in the problem changes with each submission, testing different answers by changing significant figures isn't possible. As for the Death Star, I didnt mean "look up" information...

I know it was incorrect through the submission software. Other than a math error, looking over it, the best guess I have as to why it's wrong is that I need to do one more step of subtraction. I'd need to check for other formulas to see if I have enough information, but if I could solve for...

Oops, that's not a work mistake, just a typo I forgot to check. The online program that gives the homework changes the data/values after each submission, so the problem statement has a new value of 3500, but my work is for 4500. I'm trying to correct my work, then I can start over with the new...

***NOTE: The data in my written work & the typed variables under "all known data" are correct. The problem statement has new values for a new submission, but I am trying to correct my work on an old submission. Sorry for the confusion! 1. Homework Statement Problem: All known data: Period (T)...

Here is updated work with a logical equation. I solve for change in volume (m3). Then, I can use the formula height = Volume(m3) / area (m2) to get my final answer, by plugging in the volume value and the surface area given in the problem.

Yes I did, here's the updated work: I submitted this answer (online submission) and it was correct! Thanks so much for your help!

Ignore the top part of that, just scribble...

Ah, yes, the ΔT goes away. Am I able to divide the ΔV by the surface area to get my units to m for height as I did below?
