AI Thread Summary
The discussion revolves around a physics problem involving a circular amusement park ride, where the goal is to find the velocity of a chair attached to a massless chain. The ride has a diameter of 8.0 meters, and the chair, weighing 10 kg, is connected by a 2.5 m chain at an angle to the vertical. The user expresses confusion about the necessary equations, including centripetal force and angular velocity, and feels they lack sufficient information to solve the problem. An attachment meant to clarify the problem is pending approval, preventing others from viewing it. The user seeks guidance on how to approach the problem effectively.

Alright I had a midterm in my physics class today, and was completley stumped on this problem. Either I'm missing an equation or just not getting it, if you could lead me in the right direction i'd appreciate it. I also am attaching a picture of the problem that I drew in paint.

Homework Statement


The problem states that the circular ride platform has a diameter of 8.0 meters and the 2.5 m "massless chain" is attached to the chair at an angle theta to vertical. The chair is 10 kg, what is the velocity? I know I forgot to put the decimal points in the attached drawing, it should not make much of a difference either way.


Homework Equations


Fc = m*v2/R
v = omega*R


The Attempt at a Solution


I do not have enough givens for either of these equations.

It seems like something is wrong with the attachment because I cannot open it (no link).
 
it says the attachment is pending approval.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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}...
