Since you're dropping the book with an initial velocity, and the rest of the falling path is accelerating, the velocity at any moment can be calculated, as you know, with: v = v0 + at This, however, is the velocity. If we want the distance, we have to multiply by t (vt=s) v = v0 + at /*t s =...

Right, that came to my mind in the beginning but I didn't want to work with equation systems, but it's all ok. I'd add the equation: 75 = v0*t - a*t^2/2 t = total time which we don't know, nor do we know the a so I replace: 75 = v0*t - v0*t/2 (a = v-v0/t -> in this case, v=0, so it can be...

NOTE: This is no homework, just me having fun with physics, maths, logics etc. Do not take this problem as priority, there are surely more serious and urgent problems out there! Homework Statement A passenger standing beside the railway noticed that the first wagon of the electric train...
