AI Thread Summary

The gravitational potential energy (GPE) of a 75-kg pilot at a height of 1.2 km can be calculated using the formula GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height. The confusion arises from the phrase "compared to the plane," which may imply that the height of the plane is considered as the reference point, making it zero. If the plane is at the same height, the pilot's GPE relative to the plane would indeed be zero at the moment of jumping. However, if calculating absolute GPE, it remains significant at 1.2 km. Clarifying the reference point is essential for accurate interpretation of the problem.

A 75-kg pilot jumps from a damaged plane at a height of 1.2 km. At the instant he leaves the plane, what is his gravitational potential energy compared to the plane?

So i know how to do the problem, but I am cofused because of the words "compared to the plane". Does that mean that the h is 0?

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}...
