Two Objects Are Moving in the Xy-Plane

question 32

Multiple Choice

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 = (2.3 m/s) + (4.2 m/s) and object B has a mass of 2.9 kg and has a velocity = (-1.8 m/s) + (2.7 m/s) . Some time later, object A is seen to have a velocity ' = (1.7 m/s) + (3.5 m/s) . What is the velocity of object B at that instant?

• A)(-3.3 m/s) + (10 m/s)
• B)(3.3 m/s) + (-10 m/s)
• C)(1.1 m/s) + (-3.5 m/s)
• D)(3.3 m/s) + (10 m/s)
• E)(-1.1 m/s) + (3.5 m/s)
