By momentum conservation-Resultant momentum after collision - Resultant momentum before collision -xA0-x221A-x2192-P12-x2192-P22

lf the two bodies moving at right angles collide and their initial momenta are ${\to P}_{1}$ and ${\to P}_{2}$ , their resultant momentum after collison is :

$_{1} - {\to P}_{2}$
${\to P}_{1} \sim {\to P}_{2}$
$\sqrt{{_{1}}^{2} - {\to P}_{2}^{2}}$
$\sqrt{{_{1}}^{2} + {\to P}_{2}^{2}}$

By momentum conservation,
Resultant momentum after collision = Resultant momentum before collision = $\sqrt{{_{1}}^{2} + {_{2}}^{2}}$

lf the two bodies moving at right angles collide and their initial momenta are →P1 and →P2, their resultant momentum after collison is :→P1−→P2→P1∼→P2√→P12−→P22√→P12+→P22

By momentum conservation,Resultant momentum after collision = Resultant momentum before collision = √→P12+→P22

lf the two bodies moving at right angles collide and their initial momenta are ${\to P}_{1}$ and ${\to P}_{2}$ , their resultant momentum after collison is :
