Transition notes:

1. The track needs to be put away or moved back far enough out of the way. The parts holding the track to the table may stay if it does.
2. The motion detector, fan cart and cables should be put away.
3. It is easier to construct this lab as you go. I tend to do it in this order:
1. Put out and construct the mini-launcher and photogates.
2. Place the 2 meter stick on the launcher to tell you where to put the clamp for the bin.
3. Get out and attach the bin to the tables.
4. Finish putting out everything else.

Equipment List:

• Loading... with the following sensors:
• 2 Loading..., with a
  • Loading... for each
    (one closest to the launcher DG1, Farthest DG2)
• Loading...(DG3)
• MiniLauncher held in place with a C-Clamp
• Cocking Rod
• Bag of 2 16 mm Steel Ball
• 2 meter stick
• Carbon Paper
• About 3 sheets of Paper, 85x11 White
• 3 pairs of Safety Goggles
• Plastic Catching Bin, Large
  • held in place with a Large Universal Clamp
  • Foam pad inside.
• 30 cm Ruler

On the TA Tables:

• 16 mm Steel Ball bag of 10.
• Carbon Paper small stack
• Disinfecting Wipes. Also place another 1 or 2 containers around the quad in a visible spot.

Notes and tests:

1. Attach launcher bracket with C-clamp on the corner of the left side of the table with the bracket hanging over the edge as much as possible. Arrange the launcher so that it aims at the bucket and can be at an angle of 20 without hitting the table
2. Align the launcher so that it will fire down a line across the middle of the table.   2-meter stick should be laid along this line.
3. Disinfect all Safety Goggles.
4. Check daily for missing balls, safety goggles, and cocking rods.
5. Start the test file “2305 Lab 3 test.cap”. Fire the ball making sure the first photogate starts the time and the second stops it. Make sur ethe trajectory was good and the time recorded is resonably short. Fire the ball making sure the first photogate starts the time and the time of flight pad stops it. Make sure the time is reasonable.
6. The most common problem is that the cables to the photogate are switched.
7. Note the hole in the bracket that the launcher is bolted into.
8. Mount the large plastic bin with a large universal clamp at the end of the table and line it with bubble wrap to stop the balls
9. There are two types of mini launcher. The older ones are easier to set up.
