    Average Rate Work
AI Thread Summary
To determine the average rate at which the elevator cable performs work on the cab, one must calculate the work done against gravity as the elevator ascends. The mass of the elevator cab is 3,000 kg, and it moves 165 meters upward in 23 seconds at a constant speed. The work done is equal to the change in potential energy, which can be calculated using the formula for gravitational potential energy. The average power output can then be derived by dividing the work done by the time taken. Understanding these concepts is crucial for solving the problem effectively.

The loaded cab of an elevator has a mass of 3.0 103 kg and moves 165 m up the shaft in 23 s at constant speed. At what average rate does the force from the cable do work on the cab?


I don't know where to begin. The answer is sin kW.

Work is what?

Did I hear you say change in potential energy? Because if I did then I'd be thinking you were on the right track already.

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}...
