A cannon ball is launched into the air with an upward velocity of 122 feet per second, from a 14-foot tall cannon. The height h. of the cannon ball after seconds can be found using the equation h=−16t^2+122t+14 .

Approximately how long will it take for the cannon ball to be 28 feet high? Round answers to the nearest tenth if necessary.
