Need Help with physics.

Alright, so I'm working on a lab report for physics and I need some help.


The Lab:
I place a ball at the top of a ramp, and a ball at the bottom of the ramp. I let the ball at the top of the ramp go, and the two balls collide. I then measure the distance of the first bounce of each ball. So what I need to figure out is what is the velocity of each of the balls in both the x and y direction. The only data I have is the resultant distance and angle of trajectory. Please help, it will be much appreciated .

 

Step 1 - Make a drawing

When the ball has come down and is about to hit the other ball, calculate the ball's momentum and kinetic energy

Then use conservation of momentum (in x and y direction separately) and energy to calculate each of their speeds.

Is there any friction?
