During a building project, a brick is dropped from a height of 1,936 ft. 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 brick to
hit the ground?
[?] seconds

11 seconds

Step-by-step explanation:

h(t) = -16t^2 + 1936

When  the brick hits the ground h = 0 so:

-16t^2 + 1936 = 0

-16t^2 = -1936

t^2 = -1936/-16

= 121

t = 11 seconds.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230
