A baseball is thrown in the air from a height of 5 feet with an initial vertical velocity of 15 feet per second. The function g(t) = -16t2 + 15t + 5 represents the height of the baseball, g(t), t seconds after it was
launched
At what time, t seconds, did the baseball hit the ground? Round your answer to the nearest tenth of a second.
