AI Thread Summary

The discussion centers on determining the safest speed for navigating a banked curve with a radius of 130 meters and a banking angle of 2.7 degrees under icy conditions. A key factor in this calculation is the friction coefficient of rubber on ice, which is critical for assessing safe speeds. The original poster initially sought information on the friction coefficient but later indicated they found the solution independently. The conversation highlights the importance of understanding friction in relation to banking angles for safe driving on icy roads. Ultimately, the focus remains on calculating safe speeds in challenging driving conditions.

The Attempt at a Solution

--------------------------------------

It seems I would have to know the friction coefficient of rubber on ice, does anyone know where I can find this? Thanks!

Nevermind, I've figured it out.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...
