Answer:
470 ft
Step-by-step explanation:
The equation for ballistic motion is usually written ...
h(t) = -16t^2 +v0·t +h0
where v0 is the initial upward velocity in ft/s, and h0 is the initial height in ft.
Filling in the numbers given in the problem statement, the equation becomes ...
h(t) = -16t^2 +160t +70
This can be rewritten to vertex form as follows.
h(t) = -16(t^2 -10t) +70
= -16(t^2 -10t +25) +70 +400 . . . . . . add and subtract 400 to complete the square
= -16(t -5)^2 +470
The vertex of the height vs. time curve is at (t, h) = (5, 470).
The maximum height attained is 470 feet.
