Reply To: Initial Velocity Generation

[valerym.m5]

by the way, here is another model where the initial speed is given with a plus sign:
+1000 mm per second

but in fact, according to calculations - the speed is NEGATIVE = - 1117 mm per second

9.9497890472e+00 0.0000000000e+00
1.0000000000e+01 0.0000000000e+00
1.0008694649e+01 -1.1772938232e+03
1.0009955406e+01 -1.1772938232e+03

i.e. a body with a given positive speed = +1000 mm per second should move up, but for some reason the body moves down?!
