A bullet of mass $m$ hits a block of mass $M$ elastically. The transfer of energy is the maximum, when
  1. $M \ll m$
  2. $M \gg m$
  3. $M=m$
  4. $M=2 m$

Solution

During elastic collision between two equal masses, the velocity of the two bodies gets interchanged so if one body is at rest, energy transfer will be maximum for $M=m$ $m_1=m_2=m$ (say)
