The height of an object off the ground, h (in feet) t seconds after it is launched into the air is given by
h(t) = −16t2 + 96t, 0 ≤ t ≤ 6.
Find the average rate of change of h over the interval
[3, 6].
( ) feet per second
Interpret your result.
During the last three seconds of the objects's time in the air, it is
falling at an average rate of (. )feet per second.
