The height (in miles) of an airplane descending from the sky is given by the function f(t)=-t^(3/2) . Find the distance travelled by the plane while descending, if it takes 10 minutes to land.

Question

anonymous · Answer

I am assuming verticle distance?

anonymous · Answer

I need to know its horizontal speed or velocity

anonymous · Answer

because it is an airplane not helicopter ...okay i'm assuming helicopter

anonymous · Answer

f(t) =t^3/2
and it took 10 minutes so height at 10 minutes before landing should be it's distance

anonymous · Answer

well -t

anonymous · Answer

:)

anonymous · Answer

can you recheck the function because according to this function, plane's on the ground at t=0

anonymous · Answer

Hell theres a minus sign too ...how can height be negative

anonymous · Answer

yes i just checked and it definitely says -t(3/2)

anonymous · Answer

then just put 10 min ...i really don't like this function I mean ...how can a airplane take off in sky .....

anonymous · Answer
