| Jun 21, 2015 at 23:22 | comment | added | gremlin | Ha, yes, it is, but there is a problem, because Fd will vary on speed. This is actual problem. The main problem that further body's speed is unknown at start. | |

| Jun 21, 2015 at 23:11 | comment | added | gremlin | Thanks, but you didn't understand me correctly. Because t is known. Maybe I should give concrete example. What I must do is to accelerate plane to the certain velocity in the some period of time. So, I must find needed acceleration and start simulation. Maybe it became clear. | |
