A body of mass `m` moving with a velocity `v` in the `x` direction collides with another body of mass `M` moving in `y` direction with a velocity `V`. They coalesce into one body during collision.

Options

A. `sqrt((mv_(1))+(Mv_(2))),tan^(-1)((Mv_(2))/(mv_(1)))`
B. `sqrt((mv_(1))+(Mv_(2))),tan^(-1)((Mv_(1))/(mv_(2)))`
C. `sqrt((mv_(1))^(2)+(Mv_(2))^(2)),tan^(-1)((Mv_(2))/(mv_(1)))`
D. `sqrt((mv_(1))^(2)+(Mv_(2))^(2)),tan^(-1)((Mv_(1))/(mv_(2)))`
