Integration Position Velocity

AI Thread Summary

The discussion centers on the process of finding position from velocity using integration, with a focus on correcting previous misunderstandings. The original poster asserts that their answer was correct while the software's output was incorrect. They present a position vector formula but express confusion regarding its validity. A key point raised is the distinction between initial conditions for position and initial values for velocity, which is crucial for accurate calculations. The thread highlights the importance of correctly applying initial conditions in integration problems.

EDITED:

My answer was right, the answer of the software was wrong :D !

So this thread should be deleted.

THANKS!

position vector = [at - (bt^3)/3 + v_x(0)]i + [(ct^2)/2 + v_y(0)]j
position vector = [at - (bt^3)/3 + a]i + [(ct^2)/2]j
This however is the wrong answer and I don't know understand why?

out?

Your initial conditions for position are not your initial values for velocity.

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}...
