A bullet of mass

m

hits a block of mass

M

elastically. The transfer of energy is the maximum, when

Options

A $M \ll m$
B $M \gg m$
C $M=m$
D $M=2 m$

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=m

m_1=m_2=m

(say)
