I have a question? What does hf = hi+Vivertical stand for? I haven't seen hf or hi or Vivertical yet in class-I just started a few weeks ago. Bob Pursley answered a question but I don't know what the abbreviations mean.
Thank you for the direction-
hf is height final, hi is height initial, Vi is initial velocity, Viv is initial vertical component of velocity, Vih is the initial horizontal component.
these are pretty standard symbols.
