While setting up a fireworks display, you have a tool at the top of the
building and need to drop it to a coworker below.
a. how long will it take the tool to fall to the ground? (hint: use the first
equation that you were given above, h(t)=-16t^2+h0

h=84 feet

While setting up a fireworks display, you have a tool at the top of the

building and need to drop it to a coworker below. Given the equation:

h(t) = -16t^2 + h0

h = 84 feet

it will take the tool to fall to the ground 2.29 time unit

-84 = -16t^2 – 0

t = 2.29 time unit

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
