Hello again, sorry for the very late reply, was busy with other subjects. I have a very high achievement in the physics assignment I was doing. :)
Thank you so much for helping me.
ok it is supposed to investigate how the weight of an object affects the time of flight.
Yes I were supposed to determine the Initial velocity and k, the spring constant I did. I actually did another equation which seems to give reasonable Vi. By the way, the assignment is due tommorow.
Thank you
Ok I'll get my head around that concept of conservation of momentum andtry to add it in my assignment. Beacuse right now we are doing projectile motion. It is a high school physics assignment.
Thank you so much for that very fine explanation, it was really helpful. I really appreciate that fine detailed explanation. I understood why the ball didn't hit in the same spot all the time. Its due to air resistance, may be friction and the energy from the spring is given out in different...
the answer that I got from that equation says the ball bearing's initial velcoity is 6m/s . well, I thought about that now and that doesn'y make any sense beacuse that is pretty fast 600cm/s . I am sure this spring loaded gun will not go more than 1.5m/s.
I have been working on this for the...
ok . I checked this website <http://www.bsharp.org/physics/recoil>
and understood what gun recoil was. Ok, so every action has an equal and opposite reaction. So when you launch something, the force taken for launch will cause a recoil in the spring loaded gun. Causing it to move back. But in...
Hi Simon Bridge, :)
Oh true. I did it in the absence of air resisitance , but I have no idea how to do it in the presence of air resistance. :confused: So, the recoil of the gun (conservation of momentum) will be differnt for different masses. Does that mean I will not be able to have the same...
Hello everyone,
I was doing some experiment using a spring compressed gun, that shoots up ball beraings. I made it using a desoldering pump and a PVC pipe,its quite small. ok, so I set it in 45° angles for maximum range. A desoldering pump has a spring inside, when you push down on top the...
