A 5.00 kg mass is moving at 4.00 m/s 30.0 degrees SOUTH of WEST and a 2.00 kg mass is moving at 3.00 m/s 60.0 degrees SOUTH of EAST .The velocity of the center of mass is (a) ,and the velocity NORTH of the center of mass is (b)

A) a = +2.17 m/s,b = -2.05 m/s.
B) a = -2.17 m/s,b = +2.05 m/s.
C) a = +2.05 m/s,b = -2.17 m/s.
D) a = -2.05 m/s,b = +2.17 m/s.
E) a = -2.05 m/s,b = -2.17 m/s.
