It is determined by the ball. however, 3 4m if you use the ones that come with the package.
A separate base is available for purchase, but it is not inexpensive in my opinion. Drilling two holes in a small block of wood (measure the spacing between the screws on the launcher) was my personal solution. A 3/16" or 1/4" drill bit, I believe, was used. You'll want a snug fit so the launcher screws don't pull out when you screw them in.
Selected User Reviews For Visual Scientifics PTPROJ Projectile Launcher
The other projectile launchers appear to be better options, as this one is weak and doesn't go far enough to be interesting.
The product was in excellent condition when it arrived.
This is not a student product! br>br>The first time I used it, I cut myself launching it - Because the machined aluminum slots that hold the firing lever haven't been filed, students will almost certainly be injured. The firing mechanism necessitates your finger actively dislodging the lever, which is held in place by a compressed spring and is extremely close to sharp metal.
Two metal balls were included in the launcher, but no hands were included. It was possible to get a copy of the guidebook. As a result, thank you, you worthless scumbags.
UPDATE: These are beginning to fail after four semesters of use. The screw that connects the barrel to the base appears to be the weak point - It's held together by two small screws that eventually come loose and can't be repaired. However, I doubt it was designed to withstand the amount of use it receives (launched 10 times per class x 30 classes per semester), so it's difficult to be critical. br>br>By the way, after a lot of testing, I found that the spring constant on these is on average 100 N/m.
- Original review: br>br> br>br>I purchased this for use in my introductory physics labs. Both projectile motion and energy conservation, I believe, will benefit from it. It came with balls that were the same size as 3/4" steel bearings I already had, which was convenient. I like that it has a variety of launch options so I can fine-tune it to my specific requirements. There are only two issues with which I am unhappy: 1) the wing nut on the side used to keep it at a constant angle does not appear to do a good job, and the launcher can easily be moved out of alignment while being loaded; 2) it is very side heavy and requires mounting to be useful. Fortunately, I have some extra boards from another project that will suffice, but keep in mind that they are not ready to use right away.
