A carpenter dropped a hammer from a rooftop 80 feet above the ground. How
long did it take the hammer to pass by the 3rd floor window that is 32 feet off the
ground? Round your answer to the nearest tenth. *
Recall the equation for falling objects: h(t)= h - 16t?
where h(t) is the height of the object in feet, at any
time t in seconds, and h, is the objects initial height in feet.
t = 16 seconds
O t = 1.7 seconds
t = 3 seconds
O t = 2.1 seconds
