How to Successfully Launch a Marble Through Two Hoops: A Projectile Physics Lab

AI Thread Summary
The physics lab involves launching a marble through two hoops using a ramp, with the hoops set at a specific distance or height. The hoops are approximately an inch and a half wide, while the marble is about three-quarters of an inch. The initial inquiry sought verification of the procedure to ensure the marble successfully passes through both hoops. Clarification was requested regarding the setup of the hoops, whether they are suspended or form part of the track. Ultimately, the original poster confirmed they figured out the procedure independently.

In my lab for physics we are given a ramp, some textbooks, and a marble. The objective of the lab is to make the marble go through two hoops (the hoops are about an inch and a half wide, the marble is about 3/4ths of an inch). Our teacher is going to give us either a specific distance from the table, or a height from the ground for the hoops. I have to do a pre-lab saying what procedure we will do in order to figure out how to make the marble go through both hoops. I sort of have an idea of what to do, but it would great if someone could just verify and explain the procedure we need to do in order to accomplish this! Thanks guys(:

Hi!
Could you please sketch first, how this is to be orchestrated? Is the marble to travel through the hoops? Or on them? do they form the track, or are they suspended in air?
Clarify that, and we'll get you going,
Daniel
 
I already figured it out! But thanks anyway, Daniel(:
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
