A projectile, fired by unknown initial velocity, lands 22.0 s later on the side of a hill, 3250 m away horizontally and 425 m vertically above its starting point. (Ignore any effects due to air resistance.)
1) What was its maximum height above its launch point?
2) What is the vertical component of its initial velocity?
3) What is the horizontal component of its initial velocity?
4) As it hit the hill, what speed did it have and what angle did its velocity make by the vertical?
