I want to know what the forking lemma is in simple terms. I've read a few academic papers which attempt to describe the lemma yet they are always too complex and sometimes vague.
Maybe a step by step outline of the lemma would suffice. Also it may help to describe the splitting lemma also.
acceleration= change in velocity/time
final velocity=initial velocity + (acceleration x time)
average velocity= (initial velocity+final velocity)/2
How do I derive the following equations from the given equations above?
displacement = .5(Vi+Vf)t
displacement= Vi(t) + .5at^2
That even sounds confusing typing it!
