A cannon ball is launched into the air with an upward velocity of 350 feet per second, from a 7-foot tall cannon. The height h of the cannon ball after t seconds can be found using the equation h-- 16+ 350 + 7. 18 A) what was the initial height of the cannon ball? feet B) How many seconds will it take for the cannon ball to hit the ground? seconds Round to 3 decimal place.)
