9. 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^2+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
