Question
When a ball is thrown in the air, the height h of a ball in feet t seconds after the ball is thrown in the air, is given by the equation height = 25t–16t²
Use the quadratic equation to determine how many seconds goes by before the ball hits the ground?

On the ground, h(t)=0
h(t)=25t–16t²=t(25-16t)=0
Solve the values of t that make h(t)=0.
h(t)=25t–16t²=t(25-16t)=0
Solve the values of t that make h(t)=0.
