A bullet of mass m hits a block of mass M elastically. The transfer of energy is the maximum, when

Options

  1. AM m
  2. BM m
  3. CM=m
  4. DM=2 m

Correct answer

C. M=m

Step-by-step 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=mm₁=m₂=m (say)
