What Is the Least Static Friction Coefficient for a Cat on a Merry-Go-Round?

AI Thread Summary
To determine the least static friction coefficient for a cat on a merry-go-round, one must analyze the forces acting on the cat. The ride has a radius of 5.4 meters and completes one rotation in 7.2 seconds, allowing for the calculation of centripetal acceleration. The centripetal force required to keep the cat in place must be compared to the gravitational force acting on it. By establishing the ratio of these forces, the minimum static friction coefficient can be derived. This analysis ensures the cat remains stationary without sliding off the ride.

Hi can someone help me on this problem.

a cat dozes around merry go round at radius 5.4 meters. the ride turns on and brought up to turning rate of 7.2 seconds in one complete rotation. how do i find the least static friction coefficient between the cat and the merry go round that will allow the cat to stay in place, without sliding out.

Compare the centripital force to gravitational force (the ratio).

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...
