Question

A juggler throws a ball into the air from a height of 5 ft with an initial vertical velocity of 16 ft/s. The function that models the height h of the ball in feet t seconds after the ball is thrown is h(t) = -16t2 + 16t + 5. How long does the juggler have to catch the ball before it hits the ground? _______ s.

Answer 1

when h(t) = 0
then use quadratic equation to solve for t

Answer 2

ok thank you
