break up chunkA final into x and y components of momentum. You immediately know that chunkB y component of momentum will be be eequal to ChunkA y, but in the opposite direction.
Now, do conservation of momentum in the x direction, and solve for chunkB in the x direction.
knowing the x, y componets of momentum of chunk B, the angle is easily found from the inverse tangent.
Two chunks of ice are sliding on a frictionless frozen pond. Chunk A, with mass mA=5.0kg, moves with initial velocity vA1=2.0m/s parallel to the x-axis. It collides with chunk B, which has a mass mB=3.0kg and is initially at rest. After the collision, the velocity of chunk A is found to be vA2=1.0m/s in a direction making an angle α=30 degrees with an initial direction. What is the final velocity of chunk B?
