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. Find the velocity of the center of mass, letting (a) = the east-west component, and (b) = the north-south component.

a = +2.17 m/s, b = −2.05 m/s.

a = −2.17 m/s, b = +2.05 m/s.

a = +2.05 m/s, b = −2.17 m/s.

a = −2.05 m/s, b = +2.17 m/s.

a = −2.05 m/s, b = −2.17 m/s.
