An object with mass m, initially at rest, explodes into two fragments, one with mass m_A and the other with mass m_B, where m_A + m_B = m.

a). If energy Q is released in the explosion, how much kinetic energy does each fragment have immediately after the collision?

b). What percentage of the total energy released does each fragment get when fragment A has four times the mass of the other?
