How Can I Build a Cost-Effective Air-Powered Projectile Launcher?

AI Thread Summary
To build a cost-effective air-powered projectile launcher using a 2-liter Coke bottle, focus on utilizing compressed air to achieve the desired range of 55 meters. Consider experimenting with different sealing methods and nozzle designs to maximize air pressure and projectile speed. Materials like PVC pipes or rubber bands can enhance the launcher’s efficiency without significant costs. Avoid using sharp objects or BBs, as they are prohibited. Creative problem-solving and material repurposing are key to developing an effective launcher on a budget.

Homework Statement



i need to built a launcher to shoot anything(no sharp object, bb bullets, or must be bigger then 5mm) out for about 55 Meters...

the only force i can use to launch the "object" is airs that are inside a 2Liter coke bottle...

every other material is ok..

PS: I am not rich...

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
