AI Thread Summary
An object released from rest falls a distance H in the first second. The question is how far it will fall during the second second. The potential solutions discussed include 2H or H^2, but there is uncertainty. The discussion emphasizes using uniform acceleration equations to find the final velocity after the first second. Understanding these principles is crucial for solving the problem accurately.

Homework Statement


An object is released from rest and falls a distance H during the first second of time. How far will it fall during the next second of time?


Homework Equations


That's what I need to know.


The Attempt at a Solution



I think it is either 2H or H^2. But I'm not sure.

again use those three uniform acceleration equations.

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}...
