Using the Ball Catcher with the
Dynamics Cart
Some experiments require the ball catcher be attached
to the PASCO ME-9430 Dynamics Cart (Plunger
Cart).
1. Hook the rear lip of the ball catcher under the rear
end cap of the Dynamics Cart. The spring plunger
on the cart must be in the cocked position. (Note
the orientation of the ball catcher. See Figure 4.)
2. Slip the ball catcher onto the Dynamics Cart. A
hole in the ball catcher should slip over the trigger
of the cart. The tabs on the sides of the ball
Catcher fit on the outside of the cart tray.

cock the cart plunger by inserting a pen cap or the
