Best ResponseYou've already chosen the best response.2\[S= ut +\frac{ 1 }{ 2 }a t^2\] use this and you are done , put t= n and t= n1

Best ResponseYou've already chosen the best response.2there will be two equations

Best ResponseYou've already chosen the best response.0right and we get : \[\large{S_n = u + \frac{a(2n1)}{2}}\]

mathslover

Best ResponseYou've already chosen the best response.0but can we prove that : \[S_n  S_{n1}=S_n\] ?

Best ResponseYou've already chosen the best response.2No because \[S _{n}\] is the distance traveled in nth second and S(n1) is the distance traveled in (n1) seconds, how could their difference be equal to distance traveled in n seconds ... think :)

Best ResponseYou've already chosen the best response.0yes very correct but the formula says S_n = u + a(2n1)/2

mathslover

Best ResponseYou've already chosen the best response.0Oh! OK, so it is S_nth = u + a(2n1)/2 ?

Best ResponseYou've already chosen the best response.0s= displacement, sorry for telling later.

Best ResponseYou've already chosen the best response.2@mathslover shall i derive the whole equation?

mathslover

Best ResponseYou've already chosen the best response.0no no I had done that

jasonxx

Best ResponseYou've already chosen the best response.2okay then where are you stuck?

mathslover

Best ResponseYou've already chosen the best response.0just confirm me that : \[\large{S_{n^{th}}= u + \frac{a(2n1)}{2}}\]

mahmit2012

Best ResponseYou've already chosen the best response.2for all sequences you can use that.

mathslover

Best ResponseYou've already chosen the best response.0@mahmit2012 how can s_n = a _1 + .... + a_n? I hope you are taking s = displacement and a = acceleration and n = seconds

mahmit2012

Best ResponseYou've already chosen the best response.2so if Sn is meant the nth distance for a traveling with constant acceleration you can use it.

Best ResponseYou've already chosen the best response.0Oh, k thanks @jasonxx I was just confused with nth and n seconds. :) Well, now I am interested to learn something new from mahmit2012. I am sure he has a good reaso for his solution

Best ResponseYou've already chosen the best response.0Any example or more explanation @mahmit2012 ?Please?

jasonxx

Best ResponseYou've already chosen the best response.2@mahmit2012 for all sequence but does it look like that this formula makes a proper sequence ? if a body is accelerated it won't be covering equal distance under under different time interval, still if you think you're right i would love to see that ...and @mathslover you're welcome

Best ResponseYou've already chosen the best response.2can distance vary according to a sinusoidial function ??

mahmit2012

Best ResponseYou've already chosen the best response.2and so on...you can have many answer for all motions.

jasonxx

Best ResponseYou've already chosen the best response.2can distance vary as per the sine rule ? if yes can you give an example i'll be very thankful

Best ResponseYou've already chosen the best response.2@mahmit2012 i'll try my best to understand your explanation but i am not sure how the function of distance is in the form of sine, which is traveling on a straight line ..thank you

jasonxx

Best ResponseYou've already chosen the best response.2and what you've done is just a differentiation of S= A sin wt twice

Best ResponseYou've already chosen the best response.2@mahmit2012 brother i just need an example of the motion, a real life example and i don't think we need to bring fourier series whilst dealing with kinematics

mahmit2012

Best ResponseYou've already chosen the best response.2All motions are related with Forier series. In one dimension or more.

Best ResponseYou've already chosen the best response.2concept of fourier series looks good whilst dealing with electric current and voltage, i am sure and i agree you have a good point

mahmit2012

Best ResponseYou've already chosen the best response.2this is the simplest motion and has just one w. for all motions you can have infinity frequencies.

Best ResponseYou've already chosen the best response.2well it says, what is the value of the difference of the distance traveled by a body in n seconds and n1 seconds in context of classical mechanics

jasonxx

Best ResponseYou've already chosen the best response.2@demitris i think if i'll keep you providing conditions i am sure it will take way too long and yes u is initial velocity, have mercy please :)

jasonxx

Best ResponseYou've already chosen the best response.2@demitris that has already been done thanks for your work tho

jasonxx

Best ResponseYou've already chosen the best response.2yes ..but the logic provided by 2mahmit2012 was having some fallacy i asked you to check that out ..but thanks for your concern
