give the derivation of the following with the help of calculus
|dw:1341500601567:dw| s is displacement v is initial velocity t is time a is acceleration
Basic Physics !
you don't need calculus (for constant acceleration). You can prove it with the help of a graph.
i have to prepare for exam .... and the question is to prove it using calculus

@biswajit_paul plz answer
OK answering it
s = ∫ v dt s = ∫ (at + u) dt s = ½ at² + ut + c s(0) = 0 0 = ½ a * 0² + u * 0 + c c = 0 s = ½ at² + ut
Gimme the medal !
\[-a=d ^{2}s/dt ^{2}=d/dt(ds/dt)\](as accelaratio is negative) \[d(ds/dt)=-a.dt\] \[ds/dt=-a.t+c\](after integrating, and c is a integration constant) as ds/dt is instantaneous velocity so when t=0 then ds/dt=v(according to your que v is initial velocity)=c so, \[ds/dt=v-at\] \[ds=v.dt-a.t.dt\] \[s=vt-(1/2)at^{2}+k\](after integrating, k is another integrating constant) now as at t=0 no distance was traversed so at t=o s=0=k so finally we proved \[s=vt-(1/2)at^{2}\]
thanks @biswajit_paul
I have assumed that the particle (or object) was under retarding motion (negative accelaration)
I have done this from the basic definition of acceleration and using calculus.
very very thanks @biswajit_paul धन्यवाद
hm..no mention
