[SOLVED] Horizontal ProjectileMotion
Divers jump off a cliff, at a height of 35m above sealevel. To land safely, they aim for 5m from the base of the cliff. What push off speed is neccesary?
Sy= -35m
Sx= 5
ay= -9.8m/s/s
Vi = ?
Not sure how to proceed, if Vfy = 0 at the end of the motion,
then vf^2 = vi^2 + 2a(s)
Adds up to vi = 0, unless I really screwed up my math.
