Alright, figured it out. Turns out I had the process down just fine, but just that when punching in the numbers on my calculator, I forgot to cube a. Thanks for the help guys!

I did. The answer I get then is 1.07E10, which is supposedly incorrect.

Hi guys, I'm not sure if I'm going about this the correct way, but it seems to be the only one that makes sense right now. The problem reads: Io, a satellite of Jupiter, has an orbital period of 1.77 days and an orbital radius of 4.22E5 km. From these data, determine the mass of Jupiter...

Hey guys, So, I'm kinda distraught over this problem because, by all accounts, I should be able to get the problem no sweat. However, it just hasn't been happening. If you could point out my flaw, I would truly appreciate it! In the problem, we are asked to find the magnitude of the...

Ok, just tried it by adding the two mechanical energies prior to the collision and that gave me the correct answer. Thanks for the help!

I understand how to calculate the mechanical energy after the collision, but how do I do it before? Do I calculate the mechanical energy of the runner, of the tackler, or do I add both their mechanical energies prior to the collision, and then compare?

Hey guys, I'm trying to complete a homework problem, but I'm not quite sure how to approach it. Here is the question: A 90.5-kg fullback running east with a speed of 4.91 m/s is tackled by a 94.7-kg opponent running north with a speed of 2.93 m/s. Determine the mechanical energy that...

Ok, the answer worked out. That was a stupid mistake on my part. Thank you for the help!

Ok, I'll reword it with the unit vectors in mind, and see what I come out with.

So, if I'm understanding this correctly, my substitution did yield the "correct" answer, it's just that the answer needs to be expressed in i and j hat notation?

Taking that into account then, may I inquire how that changes the setup of my problem-solving process? Unfortunately, I'm not seeing it right now.

Hey guys, Alright, I feel like this is super easy, but for some reason, I'm not getting the right answer. Could you guys point out my flaw? There are (one can say) three coequal theories of motion for a single particle: Newton's second law, stating that the total force on an object causes its...

That makes sense. Thanks guys!

Hey guys, I'm currently taking the first physics course right now (calculus-based physics), but it's not going as smoothly as I would've hoped. Anyways, here's one of the many questions I shall be posing on the forum: A baseball approaches home plate at a speed of 47.0 m/s, moving...
