Question

Two objects are moving in the xy-plane. No external forces are acting on the objects. Object A has a mass of 3.2 kg and has a velocity of Va= (2.3 m/s)i + (4.2m/s)j and object B has a mass of 2.9 kg and has a velocity of Vb= (-1.8m/s)i + (2.7m/s)j. Some time later, object A is seen to have a velocity Va'= (1.7m/s)i + (3.5m/s)j.What is the velocity of object B at that instant?
