the height above ground level i





n meters of a missile launched vertically ,is given by h(t)=-16t3+100t .at what time is the missile 72mabove ground level ? (t is time in seconds)






Answered by Steve
just solve for t in

-16t^2 + 100t = 72

This assumes a normal rocket trajectory under constant gravity. Not sure where a cubic function would work.
