**bobpursley**, Sunday, November 10, 2013 at 8:47pmI would use conservation of momentum in the S and west direction.

S direction

M*21S+2M*v S=0

so v in the South direction is -10.5

so the same in th eEast direction

v in the East Direction

V=-10.5 E

angle= arctan 10.5/10.5 or NE at velocity 10.5*sqrt2
