Question 76827: a hammer is dropped from a construction project 576 ft above the ground. the height h(in ft) of the hammer is mideled by the position equation h(t)=-16t^2+ 576 where t is the time i seconds. how long will take for the hammer to reach the ground? Answer by Edwin McCravy(20060) (Show Source):
a hammer is dropped from a construction
project 576 ft above the ground. the height
h(in ft) of the hammer is mideled by the
position equation where t
is the time in seconds. how long will take
for the hammer to reach the ground?
Plug in
That's because when it hits the ground its
height above the ground is 0.
Divide both sides by 16:
Take positive square roots of both sides:
Answer: the hammer hits the ground in 6 seconds.
