Object A has a mass of 50 kg and is initially moving along the x-axis at 5.0 m/s. It collides with object B, which has a mass of 22 kg initially at rest. After the collision, object A moves with a velocity of 3.0 m/s in a direction that is 30 degrees above the x-axis. What is the final velocity (magnitude and direction) of object B?
