Solve the problem.
-As part of a physics experiment, Ming drops a baseball from the top of a 330-foot building. To the nearest tenth of a second, for how many seconds will the baseball fall? (Hint: Use the formula h $$= 16 t ^ { 2 }$$ , which gives the distance h, in feet, that a free-falling object travels in t seconds.)
A)20.6 sec
B)82.5 sec
C)1.1 sec
D)4.5 sec

Using the formula $ h = 16t^2 $, set $ h = 330 $ and solve for $ t $:  $ 330 = 16t^2 $  $ t^2 = \frac{330}{16} $  $ t^2 = 20.625 $  $ t = \sqrt{20.625} \approx 4.5 $ seconds.

Solve the Problem =16t2= 16 t ^ { 2 }=16t2 , Which Gives the Distance H, in Feet, That a Drops
