Solving Vector Problems in Physics: Hot Air Balloon and Wind Velocity

AI Thread Summary
A hot air balloon is influenced by a wind velocity of 20 km/h to the east, affecting the direction of a flag held by a passenger. The flag will point downwards due to the relative motion of the wind and the balloon's velocity. The surrounding air moves with the balloon, making the flag's position dependent on the passenger's actions. The discussion raises questions about how flags behave in still air and the relevance of the passenger's velocity. Understanding the vector components of wind and balloon motion is crucial for solving this problem.

Homework Statement


A hot air balloon is carried by a wind with a velocity of 20 km/h [E]. If a passenger holds a flag out of the gondola, in what direction will the flag point?


Homework Equations





The Attempt at a Solution


The answer says down but idk why?

I suppose the wind will carry the balloon along at the speed of the wind. Therefore the air surrounding the balloon will be moving at the same speed as the balloon.

Probably whatever direction the passenger wanted to point it.
 
Which way do flags hang when there is no wind?
 
Is the person traveling equivelocity relevant to the wind in the gondola? Imagine being in a convertible if that helps you picture it intuitively.

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}...

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...
