Homework Statement
A 0.321 kg puck, initially at rest on a horizon-
tal, frictionless surface, is struck by a 0.227 kg
puck moving initially along the x-axis with
a speed of 2.51 m/s. After the collision, the
0.227 kg puck has a speed of 1.51 m/s at an
angle of 31 degrees to the positive x axis.
Determine the velocity of the 0.321 kg puck
after the collision. Answer in units of m/s.

The Attempt at a Solution
I do not understand collisions at all. My teacher didn't go over this and reading about this online is confusing the hell out of me, especially since I can't find an example of hitting something at rest and going off at an angle online so I have no idea how I'm supposed to solve this.
