Kathy Cohen · Answer 1

For this case we have the following equation:

-16t + 8t + 8 = 0

The first thing we must do is rewrite the equation correctly.

We have then:

-16t ^ 2 + 8t + 8 = 0

Solving the polynomial we have:

t1 = - 1/2

t2 = 1

We discard the negative root because we want to find the time.

Answer:

it takes for the object to reach the ground а bout:

t = 1 second
