Question
Projectile Motion A ball is thrown upward from the top of a building. Its height $h$, in feet, after $t$ seconds is given by the equation $h=-16 t^{2}+96 t+200 .$ How long will it take for the ball to be $88 \mathrm{ft}$ above the ground?
Step 1
We are asked to find the time it will take for the ball to be 88 feet above the ground. So, we set $h$ equal to 88 and solve for $t$. $$-16 t^{2}+96 t+200 = 88$$ Show more…

Height of a projectile: The height of an object thrown upward from the roof of a building $408 \mathrm{ft}$ tall, with an initial velocity of $96 \mathrm{ft} / \mathrm{sec}$, is given by the equation $h=-16 t^{2}+96 t+408,$ where $h$ represents the height of the object after $t$ seconds. How long will it take the object to hit the ground? Answer in exact form and decimal form rounded to the nearest hundredth.
