Answer Key / Explanation : (d) -
|
(d) Let
For elastic collision, Newton’s experimental formula
Solving Eqs. (i) and (ii), Fractional loss in K.E.
The transfer of energy is maximum (or 100%) when
That is the transfer of energy is maximum when the mass ratio is unity |
be the initial velocity of the ball of mass
. Then
(i)
(ii)
