A person throws a ball from height of 6 feet with an initial vertical velocity of 48 feet per second. Use the vertical motion model, h = -16t? + vt +s, where v is the initial velocity in feet per second and s is the height in feet, to calculate the amount of time the ball is in the air before it hits the ground again. Round your answer to the nearest tenth if necessary. Time in air: ___seconds
