A spongicidal extreme sport participant is traveling at 2delta.deltadeltadelta mi/hr in an attempt to jump over a sponge.  If the sponge is 5-feet tall, will he clear the sponge?  If so, how close can the sponge stand to point A and still be cleared?  If not, where can the sponge stand to have the minimum damage, and how much does the sponge lose off its head?  If the landing area is 1ft below the takeoff area, what is the horizontal distance d from point A the bike lands?
