Answer:
The highest altitude of that object is 1,600 feet.
Step-by-step explanation:
Given that,
where h(t) is the height of the object after t seconds.
Differentiating with respect to t
h'(t)= -32t+192
Again differentiating with respect to t
h''(t)= -32
To find the maximum or minimum value, first we set h'(t)=0.Then we get a equation of t and solve it. Assume t=a is the solution of the equation .
Now check h''(t) at t=a, if h''(a)<0 then the function h(t) has a maximum value at t=a
If h''(a)>0 then the function h(t) has a minimum value at t=a.
Now,
-32t+192=0
⇒32t=192
⇒t= 6
h''(6) = -32<0, So the object reaches at its highest altitude after 6 seconds.
Now plunging t=6 in the given function
h(6)= -16 (6)²+192×6 +1024
=1600 feet
The highest altitude of that object is 1,600 feet.
