Question

All ball of mass $m_{1}$ collides elastically and head on with another ball of mass $m_{2}$ initially at rest. In which of the following cases transfer of momentum will be maximum?

• A. $m_{1}>m_{2}$
• B. $m_{1} < m_{2}$
• C. $m_{1}=m_{2}$
• D. Cannot be predicted

Answer 1

Answer: (C)

$m_{1}=m_{2}$

Answer 2

Transfer of kinetic energy and hence, momentum is maximum when $m_{1}=m_{2}$ .
