Question

Derive the equation of motion
V2 = U2 + 2as (2)
OR
S= ut + at2/2
Where all symbols have usual meanings​

Answer 1

Answer:

From the first equation of motion,

v=u+at

t=av−u...........(i)

For a uniformly accelerated motion, Average velocity=2v+u...........(ii)

Displacement=Average Velocity×Time

Substituting from (i) and (ii),

s=(2v+u)×(av−u)

∴v2=u2+2as
