Relative Velocity and Acceleration Example (Part 2) - Engineering Dynamics

Calculating the relative velocity and relative acceleration of two particles. Part 1 - Calculating the relative velocity using a scalar formulation and geometry. Part 2 - calculating the relative acceleration using a vector formulation.

Thank you sir, this has been a great help. Love your energy and structure free attitude with such a great structure for solving the problem, great irony.

[@PrinceAbubu59]

That was a really cool problem. And really clear explanation to understand. Thanks!!:D

[@MunaNuxay]

using this for my revision its LIT!!!!!!!!!!!!!!!!!!!!!!

[@nyahothloangbipean92]

Thank you so much. This was very helpful.

[@AzzaimAnuar]

Much appreciated. This helped me quite a bit. Cheers

[@MariiBonham]

Dude I can't even begin to thank you, this helped a lot with this topic and my exam is today and I've been justso frickin nervous bc my professor is like way too complicated anyways thank youuu

[@bbhulk25]

I watch A LOT of your videos.. they are all great! thanks!

[@Hisham23633]

howcome when i use the cosine law and sine law i get slightly diffrent answers?

[@structurefree]

word! i love dynamics!

[@Dillyboyz]

this is the detail i wish my profs went into. many thanks from cal poly!

[@unrolodeporai]

Thank you. This really helped me understand this topic better.

[@structurefree]

+unrolodeporai you are welcome!

[@unrolodeporai]

+structurefree I got 100 on my weekly quiz this week cause of this!

[@jesussaquin6266]

Nvm I understood that you solved for relative acceleration by breaking it down into its respective x and y hat components but how would we solve for magnitude of acceleration

[@jesussaquin6266]

why cos45? i thought acceleration was aNormal plus aTangent which equals acceleration vector for particle A

[@raphaelmadu9197]

if you use the scalar approach it will give you a different angle

[@jesussaquin6266]

i wish you did velocity with vector decomposition

[@10hoda]

can it be solved as a triangle like V (A/B) the one before it ? cuz i got a wrong number while doing so

[@NewOryx-z1t]

Same question. When I solve it with triangles I get a(A/B) = 3.81m/s². Didn't calculate the angle ('cause i know the length is wrong)

[@jonscattargia2888]

Very helpful thank you!

[@joulefiftyfive3809]

Thanks man! Awesome.

[@Tokinjoker1]

Can't figure out for the life of me how you got horizontal component or the vertical component. 0.828 or 4.24. How is calculated?

[@2012bigfan]

dude!!! you're like tottaly awesome!! Thanks a bunch

[@N3wschooler]

nice, thanks

[@manicpixiedreamgirl7930]
