Two chunks of ice are sliding on a frictionless frozen pond. Chunk A, with a mass ma= 5.0 kg, moves with initial velocity va1= 2.0 m/s parallel to the x-axis. It collides with chunk b, which has a mass mb= 3.0 kg and is initially at rest. After the collision, the velocity of chunk A is found to be Va2= 1.0 m/s in a direction making an angle a= 30 degrees with the initial direction.

What is the final velocity of chunk B?

1. find the initial momentum of A in the x and y directions
... then, find the final momentum of A in the x and y directions
... the difference, in x and in y, is the momentum imparted to B

use B's x and y momenta to find its final velocity
