Andru [333]

Answer:

h = 2.25 m

Step-by-step explanation:

=> h = \frac{(12)^2}{2(32)}

=> h = \frac{144}{64}

=> h = 2.25 m

It is in the air 5.625 seconds.

Using the quadratic formula,

t=\frac{-b\pm \sqrt{b^2-4ac}}{2a}&#10;\\&#10;\\=\frac{-90\pm \sqrt{90^2-4(-16)(0)}}{2(-16)}&#10;\\&#10;\\=\frac{-90\pm \sqrt{8100-0}}{-32}&#10;\\&#10;\\=\frac{-90\pm \sqrt{8100}}{-32}=\frac{-90\pm90}{-32}&#10;\\&#10;\\=\frac{-90+90}{-32}\text{ or }\frac{-90-90}{-32}=\frac{0}{32}\text{ or }\frac{-180}{-32}&#10;\\&#10;\\=0\text{ or }5.625

0 is when the ball is first launched, 5.625 is when it hits the ground again.
