Installing the 2-Dimensional Collision Attachment
The two dimensional Collision Attachment consists of
2 screws, 2 nuts, and a flat plastic bar. It is used with
the Mini Launcher to hold a second ball in front of the
muzzle so the launched ball will collide with the
second ball, creating a 2-dimensional collision.
Assembly
To assemble the collision attachment , insert the
screws through the holes and secure with the nuts as
shown in the following illustration.
To mount the collision attachment to the Launcher the
square nut slides into the T-shaped channel on the
bottom of the Launcher. (See Experiment Figure 6.2)

Expectations for the Mini Launcher
The following are helpful hints and approximate
values you may find useful:
➀ The muzzle speed will vary slightly with angle.
The difference between muzzle speed when shot
horizontally versus vertically can be anywhere
from zero to 8 %, depending on the range setting
and the particular launcher.
➁ The scatter pattern is minimized when the Mini
Launcher base is securely clamped to a sturdy
table. Any wobble in the table will show up in the
data.
➂ The angle of inclination can be determined to
within one- half of a degree.
