i found the net loss in kinetic energy my mistake in that
did u understand now
one doubt how u could make the final as mu^2/9
i did not understand what u asked
like for the final KE you took velocity as u^2/9
how
i found that velocity after collision of the object that crashed(v1) is v/3 check pic 1
ok got it
thx
welcome
