Arock is propelled upward from the top of a building 180180 feet tall at an initial velocity of 200200 feet per second. the function that describes the height of the rocket in terms of time t is f (t )equals negative 16 t squared plus 200 t plus 180.f(t)=−16t2+200t+180. determine the maximum height that the rock reaches.

The maximum height reached = 805 feet

Explanation:

The height of the rock in terms of time t is f(t)=−16t²+200t+180

At maximum height f (t) is maximum, at maximum f(t) we have f'(t) = 0

That is

At time t = 6.25 s the rock reaches at maximum height,

Substituting in f(t)

                  f(6.25)=−16 x 6.25²+200 x 6.25 +180 = 805 feet

The maximum height reached = 805 feet

the answer would be a

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
