Asoccer ball is thrown upward from the top of a 204 foot high building at a speed of 112 feet per second. the soccer ball's height above ground can be modeled by the equation . when does the soccer ball hit the ground?

8.5 seconds to hit the ground

Step-by-step explanation:

A soccer ball is thrown upward from the top of a 204 foot high building at a speed of 112 feet per second.

Vo is the speed 112 feet per second

h0 is the initial height = 204 foot

So the equation becomes

When the soccer ball hit the ground then the height becomes 0

Apply quadratic formula

time cannot be negative

so it takes 8.5 seconds to hit the ground

answer: add the !

step-by-step explanation: then we will answer

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
