An asteroid, initially at rest, explodes into three pieces. One part has a momentum of $8530$ kg m$/$s $[$E$]$ and another has a mass of $2780$ kg with velocity $12\mathrm{.}9$ m$/$s $[$W $12$ degree S$].$ The mass of the third part is 

$375\mathrm{.}00$ kg$.$ What is its total velocity and total kinetic energy?
