Suppose you throw a ball straight up from the ground with a velocity of 80 ft/s. As the ball moves upward, gravity slows it. Eventually the ball begins to fall back to the ground. The height h of the ball after t seconds in the air is given by the quadratic function:
h(t)=−16t2+80ta. How hight does the ball go?
b. For how many seconds is the ball in the air before it hits the ground?
a. The ball goes 100 ft.
b. The ball is 5 seconds in the air before it hits the ground.
a. The ball goes 110 ft.
b. The ball is 8 seconds in the air before it hits the ground.
a. The ball goes 105 ft.
b. The ball is 5.5 seconds in the air before it hits the ground.
