Non-uniform circular motion (i think)

AI Thread Summary
The discussion focuses on calculating the tangential acceleration and velocity at which a hollow tube breaks while a steel block rotates on a steel table. The block, weighing 600 g, is subjected to a thrust force of 4.81 N, and the tube can withstand a maximum tension of 60.0 N. Participants suggest determining the speed that causes the tube to reach its breaking strength through centripetal acceleration. Additionally, they emphasize the importance of calculating the tangential acceleration to find the time required to reach this breaking speed. Overall, the calculations involve understanding the forces at play and the effects of kinetic friction between steel surfaces.

I guess I need to find a tangential acceleration or something and and velocity at which the tube breaks and also a time it takes to get to that velocity, but I'm not sure. Can anybody help please?

A 600 g steel block rotates on a steel table while attached to a 1.20 m-long hollow tube. Compressed air fed through the tube and ejected from a nozzle on the back of the block exerts a thrust force of 4.81 N perpendicular to the tube. The maximum tension the tube can withstand without breaking is 60.0 N. If the block starts from rest, how many revolutions does the block complete before the tube breaks?

Do you have a picture? In what plane is this rotating? What exactly does the nozzle do?
 
well i guess since it is a steel table it is rotating along the tangential axis, and here is the pic that i have. this pic along with what the problem is all the info I have. I also think that u have kinetic friction, so if that is the case, then the coefficient for steel on steel without lubrication is 0.6 (according to my physics book) so u can maybe use that.

You need to do two things:
(1) Determine the speed that requires the tube to exert a force equal to its breaking strength. Hint: Centripetal acceleration.
(2) Determine the tangential acceleration and use it to figure out how long it takes to get to the breaking speed.
 

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}...
