I need to use the given equations to derive the equation for final velocity.

AI Thread Summary
To derive the equation V2x² = V1x² + 2axΔt, the key is to eliminate the variable Δt from the given equations V2x = V1x + axΔt and ΔX = V1xΔt + 1/2axΔt². The discussion emphasizes the need to correctly identify which variable to eliminate to achieve the desired result. Additionally, there is a note that the initial statement of the final equation contains an error. The focus is on applying algebraic manipulation to arrive at the correct equation.

Welcome to PF.

What variable do you need to eliminate from the equations you are given to get the answer? (Btw, your statement of the final equation is in error.)

Armed with that ... it's Nike time ... just do it.
 

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}...
