    Distance traveled
AI Thread Summary
The discussion centers on understanding the calculation of distance traveled during the nth second, which is derived by subtracting the distance covered in the first n-1 seconds from that of the first n seconds. This method highlights the specific distance an object travels in that particular second. There is skepticism about the necessity of this equation, especially considering its limitations with varying time units. The conversation reflects confusion over the relevance and application of this concept in physics. Overall, the distinction between the nth and (n-1) second is crucial for precise calculations in kinematics.

I dont understand what this mean lol
Relevant Equations
S = S_o + v_o + \frac{1}{2}at^2

Hi! I don't understand why is made the difference between the n second and the (n - 1) second. Can anyone help me? Thanks!

The distance traveled in the nth second is the distance traveled in the first n seconds minus the distance traveled in the first n-1 seconds.
But why anyone would bother to develop such an equation (to be remembered?) is beyond me, especially since it breaks down if using different units for time.

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...
