How Do I Double Integrate Discrete Acceleration Data to Find Displacement?

AI Thread Summary
To double integrate discrete acceleration data for displacement, start by creating a third column for instantaneous velocities using the acceleration data. This involves integrating the acceleration values over time intervals to compute velocity. Next, apply the same integration process to the velocity data to derive displacement values for each time interval. Finally, sum these displacements to obtain the total displacement. This method effectively transforms the discrete acceleration data into meaningful displacement information.

I understand that I need to double integrate to convert acceleration signal to displacement signal. If I have an acceleration signal at discreet times (no algebraic realtion to relate accelration to displacement), how do I double integrate? In other words i just have 2 colums, one with time and the other with acceleration. How do I double integrate? Please advice

Can you, from the two existing columns, generate a third column that lists "instantaneous" velocities at those times ? Once you do that, repeat the algorithm to generate displacements for each interval. From these last numbers, you should be able to find the total displacement.
 

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}...
