Angular Angular velocity Spinning Velocity Wheel

AI Thread Summary

To determine the maximum angular velocity of a turntable without a coin sliding off, the static friction coefficient of 0.810 is crucial. The centripetal force required to keep the coin in place is provided by the frictional force, which can be calculated using the formula involving mass, radius, and angular velocity. By setting the frictional force equal to the centripetal force, the maximum angular velocity can be derived. The solution involves substituting the known values of mass, radius (16.0 cm), and static friction coefficient into the equations. This approach ensures that the coin remains stationary relative to the turntable during its rotation.

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 '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 'Understanding Forces and their Vector Components'

I was told forces are vectors so they can be divided into x and y components, but what about the normal force or the force of static friction? do you divide those into x and y components if say you had a block that was lying on an angled surface?
