This again looks like a partial document. I'll check your email, but I'll have to do that at VHCC so it might be Monday before I can do it.
Your analysis so far looks good.

When I sent this the first time it was complete. I am not sure why you only got part of it. I will try again. I also emailed this to you on wednesday.
Steel Ball, Marble, and Ramp Collision ExperimentPurpose:
The purpose of this lab is to determine if the extra millimeter added by the metal strap will affect the kinetic energy after the collision. Procedure:
Set up a ramp system so that a ball will roll from the starting position, down the ramp onto another ramp and off the edge of the lab table. Place paper on the floor to record projectile range and place carbon paper in the vicinity of the fall. Roll the steel ball down the ramp and off the table to record the range of the steel ball alone. Place a marble carefully on a straw so that the centers of the two balls will be in a horizontal plane. Roll the steel ball down the ramp and allow collision with the marble. Record the range of the steel ball and the marble as they hit the floor. Now raise the ramp system a millimeter by placing a metal strap under the ramps and repeat. If the centers of the two balls were in a horizontal plane before, this will no longer be the case. The goal is to determine if the difference due to the extra millimeter is detectable.
Data:
Ramp (no strap/first setup)
33.1 cm undeflected steel ball
30.0 cm deflected steel ball
59.6 cm target ball
Vave steel ball before collision = ’ds/’dt = 33.1cm/.43s = 76.98 cm/s
