Equations of motion Definition and 210 Threads

Dear All, Currently I'm working out a formula for Destroyers in the online game BattleGround Europe to be able to blast inland towns with their deck guns. To do this I've had to use the equations of motion. I could use some help on dechipering the final part of the clue. Points to note are...

dE*dE/(dt*dt) -dE*dE(k*L*L/m)/(dx*dx)=0 m-mass L-distance beetween mass point

Equations of Motion Help! I have been working on this for awile and still can't figure it out. What equation would I use to solve this problem? Here is the problem: On a ride called the Detonator at Worlds of Fun in Kansas City, passengers accelerate straight downward from zero to 45 mi/h...

Two physics students conduct the following experiment from a very high bridge. Thao drops a 1.5kg shot put from a vertical height of 60m while at exactly the same time Benjamin throws a 100g mass with an initial downwards velocity of 10 m/s from a point 10m above Thao. At what time will the...

Departing from the Navier-Stokes equations for an incompressible flow (with \rho and \mu=\rho \nu constant): \frac{Du_i}{Dt}=\frac{\partial u_i}{\partial t}+u_j \frac{\partial u_i}{\partial x_j} = -\frac{1}{\rho} \frac{\partial p}{\partial x_i} +\nu \frac{\partial^2 u_i}{\partial x_j^2}...

If I got v=u+at i get, \int v = \int (u+at) dt which is s=ut+\frac {1}{2} at^2 + C how do i explain away the integration constant in this derivation?

The question: A 2-kg point mass is welded on the interior of a 2-kg thin ring at point P. The ring has a radius R = 160 mm and rolls on the surface without slipping. (a) Draw a free body diagram for the ring and point mass. Develop the equations of motion for the system. (b)...

I'm studying Lagrangian Dynamics using a Schaum's Outline. This book seems to assume that the student can easily set up the Differential Equations of motion, but I can't seem to get the hang of it. The book does not give any actual methods or examples for setting up these Differential...

DEAR MEMBERS, I AM LEARNING THE EQUATIONS FOR MOTION, AND WE ARE TAUGHT 'SUVAT' BUT I DON'T QUITE UNDERSTAND WHY I NEED ALL 4 OF THEM AND WHAT EACH IS USED FOR ? FOR EXAMPLE : V^2 = U^2 + 2AS WHERE DOES THE SQUARE COME FROM ? PLEASE HELP ME. FROM ROGER :cry:

Ok, so I am dealing with a critically damped oscillator in which the natural frequency(w) of the oscillator is equal to the coefficient of friction (y). I am given the force mfe^t and told to find a solution for x, where x'' +2yx' +w^2 =fe^t. How do I go about doing this? The solution...
