fucking hero ! thanks <| sep |> First questionIf acceleration is constant , then displacement x as a function of the time t is x x 0 vt 0 . 5 at 2 where x 0 is the displacement at t 0 , v is the velocity at t 0 and a is the acceleration . There are 3 undetermined parameters here x 0 , v and a , but you are given 3 possible values for t , x . This is exactly sufficient for solving for unique values for x 0 , v and a just substitute the t , x values into above and you have 3 simultaneous equations . <| sep |> in some cases you dont know when a post will take off . Ive woken up to many pages of inbox replies unexpectedly before . I keep them there as i like to read every one to continue interesting conversations . <| sep |> yeah , but you can join multiple networks and switch active ones at any point . I ' m in like 6 .
