Question

who knows 2 derieve the equation of motion"v^2=u^2+2as

Answer 1

i bet there arent many!!!!

Answer 2

u guys fail 2 me hahhaha

Answer 3

s=vt
v=u+v/2
s=((u+v)/2)/t--1
we know that v=u+at--2
plugging that in equation 1
s=[(u+u+at)/2]/t
s=[(2u+at)/2]/t
s=ut+1/2at^2--3
from equation 2
v^2=(u+at)^2
v^2=u^2+2uat+(at)^2
v^2=u^2+2a(ut+(1/2)at^2)
using equation 3 we have
v&2=u^2+2as

Answer 4

hreat which grade r u???????

Answer 12

oh tats y
i know it now itself!!!!!!
derievation
i am just 6th

Answer 13

good:)

Answer 14

what a humble kid

Answer 15

Alternatively, by the Work-Energy theorem)
(change in energy) = (work) = (Force).(displacement force applied)

\[\frac{1}{2} m v^2 - \frac{1}{2} m u^2 = F s = mas\]

Canceling m throughout and multiplying by 2
\[v^2 - u^2 = 2as\]
