How long would it take for an egg dropped from a helicopter to fall 256 feet to the ground? d=16t^2
schepotkina [342]
Well the position function is:

h(t)=-16t^2+256

It will hit the ground when h(t)=0

-16t^2+256=0  factor out -16

-16(t^2-16)=0  factor difference of squares...

-16(t+4)(t-4)=0, since t>0

t=4 seconds
