A swim team member performs a dive from a 14-foot high springboard. Her path is represented by the equation h(t)=-0.875t^2+5.25t+14 where t is time in seconds and h is the height above the surface of the water. She needs to finish her flip no later than 5 feet above the surface of the water in order to prepare for the splash. What time does this happen? Round to the nearest tenth of a second.
