Are you sure the area is 0.0003 m^2? Diameter = 2 cm -> r = 0,01 m 4*π*r^2 = 0,00126 m^2 0,00126 / 2 = 0,0006 m^2

Velocity in vacuum should be: 4.429447 m/s Sorry for this fault in my first post. So, with the drag, the velocity is slower after all. But yes, the different is not much for just 1 meters. But at least I might have some idea for how the velocity at impact should be around 1 or 3 meters.

Hi, I did my best and tried something in excel. I would like to ask you guys to have a look at it to see if I did the correct thing. If so, my problem has been solved :). However, the drag due to the tube has not been calculated, indeed this should matter though. Anyway, just to assume...

It's for a project at my study where we are doing experiments for a company that makes a new material which we have to test on different kind of properties. One of these experiments is an impact test (to see a visual property). As the experiment has been developed by other students a long time...

I see. Thanks for your comment. Unfortunately, I don't know much about integrating so I find it very difficult. So it would be really great if one could help me out with that, or at least give an example how I can solve my question. Thanks

Hello, I have got an question. How can I calculate the velocity of an object which I'll drop from a height of 1 meters with a starting velocity of 0 m/s? I did some research myself and found out that I can calculate this with using the following formula: St = 0.5 * 9.81 * t^2 St =...
