F o r space p a r t i c l e space A comma space
A f t e r space 10 s comma space
stack r subscript A with rightwards arrow on top space equals 4 space i with hat on top minus 4 j with hat on top plus 7 stack k space with hat on top plus space 0.4 i with hat on top cross times 10

S i m i l a r l y space f o r space p a r t i c l e space B comma space a f t e r space 10 space s comma space

stack r subscript B with rightwards arrow on top space equals 2 space i with hat on top plus 2 j with hat on top plus 5 stack k space with hat on top plus space stack v subscript B with rightwards arrow on top space cross times 10 space

A f t e r space c o l l i s i o n comma space

stack r subscript A with rightwards arrow on top space equals space stack r subscript B with rightwards arrow on top space
4 space i with hat on top minus 4 j with hat on top plus 7 stack k space with hat on top plus space 0.4 i with hat on top cross times 10 space equals space 2 space i with hat on top plus 2 j with hat on top plus 5 stack k space with hat on top plus space stack v subscript B with rightwards arrow on top space cross times 10 space

S o l v i n g space w e space g e t comma space
stack v subscript B with rightwards arrow on top space cross times 10 space space equals 8 space i with hat on top minus 4 j with hat on top plus 7 stack k space with hat on top minus space space 2 space i with hat on top plus 2 j with hat on top plus 5 stack k space with hat on top space equals 6 space i with hat on top minus 6 j with hat on top plus 2 stack k space with hat on top
stack v subscript B with rightwards arrow on top space equals space fraction numerator 6 space i with hat on top minus 6 j with hat on top plus 2 stack k space with hat on top over denominator 10 end fraction space equals space 0.6 space i with hat on top minus 0.6 j with hat on top plus 0.2 k with hat on top   
 
Velocity of second particle is 0.6 space i with hat on top minus 0.6 j with hat on top plus 0.2 k with hat on top
