Britney throws an object into the air with an initial vertical velocity of 27 feet per second from a platform that is 10 feet above the ground. about how long will it take the object to hit the ground? 1 second 2 seconds 3 seconds 4 seconds

Hi!

So assuming that the coefficients of the acceleration is -16, this is how it would go:

-16x^2 is the acceleration

27x is the initial vertical velocity

10 is the initial height

so it would be set up as -16x^2 +27x +10

the best way would be to graph it and find the zeros and use the positive one

Or you can plug the answer choices in for x and see which answer makes the y come out to be 0

As you can see in the picture below. the point that crosses at the x-axis is 2

So your answer is 2!

I hope this helps and I am very sorry if this is wrong!
