ans is C?

now,

<v>² = ₀âˆ«¹V²t²dt + ₁âˆ«²(v/2)² .dt

=><v>² = v²/3 + v²/4 = 7v²/12

this is in 2secs.

in 1 sec,

<v>² = 7v²/24

so <v> =√7v²/24 = v√7/24

[thanx .. i had forgottn this kinda questions.. ur q reminded me abt this afetr a long time :)]

i told u sky u have great brain(s)......

fantastic work sky [1]
