AI Thread Summary

Applying brakes slowly on slick roads is crucial to prevent skidding, as sudden braking can lead to loss of traction. When brakes are applied gradually, it allows for better control of the vehicle and reduces the likelihood of locking the wheels. This is due to the principles of friction and momentum; gradual braking maintains a balance between the forces acting on the vehicle. Additionally, it helps to distribute weight more evenly, enhancing stability. Understanding these concepts can significantly improve safety while driving in slippery conditions.

What do you think?

So you don't skid homeslice!

Of course, you would still need to tell why applying the brakes slowly will prevent skids!

I still need a good explanation in words, using concepts of forces. The commonsensical explanation of skidding does not help a lot.
Thanks anyways. I hope somebody will answer this.

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}...
