Question

Zach throws a ball upward so that it follows the equation

y= 16x^2 + 64 +5 where y is the height of the ball and x is time.
How many seconds will it take for the ball to hit the ground?

Answer 1

Hey there!

=> y= 16x^2 + 64 +5

Let's obtain a formula for x

=> y= 16x^2 + 64 +5

=> y=16x^2+69

=> y - 69 = 16x^2

=> y - 69/16 = x^2

=> y - 4.3125 = x^2

=> x = √y - 4.3125

=> x = y - 2.08
