A quarter falls off a building that is 144 feet tall. If the equation for height as a

function of time is

h(t) = -16t2 + initial height where t is

time in seconds and h(t) is height in

feet, how many seconds will it take for

the quarter to hit the ground?

3 seconds

Step-by-step explanation:

Initial height = 144 feet

t = Time taken

The equation of the height from the ground is

The time taken to reach the ground is needed. Here the ground is taken as reference so

So, time taken by the quarter to reach the ground is 3 seconds.
