A particle of mass M which is at rest splits up into two. If the mass and velocity of one of the particles are m and v respectively, calculate the velocity of the second particle
\(\frac{mv}{M}\)
\(\frac{Mv}{M - m}\)
\(\frac{mv}{M + m}\)
\(\frac{mv}{M - m}\)
Giải thích
(M - m)V2 = mv
V2 = \(\frac{mv}{M - m}\)
V2 = \(\frac{mv}{M - m}\)
