A baseball player throws a ball with an initial vertical velocity of 55 feet per second from a height of 6.5 feet. Use the vertical motion model, h = -16t^2 + vt +s where v is the initial velocity in feet per second and s is the height in feet, to calculate how long the ball will be in the air for. Round your answer to the nearest tenth.​
