A water balloon was launched
into the air from the top of a hill
38 feet above ground. The balloon's
path is represented by the equation
h(t) = -16f² +48t + 38, where h(1)
represents the height, in feet, and
is the time in seconds. Find the
average rate of change from the
initial launch to the maximum height.
A) 24 ft/sec
B) 28 ft/sec
C) 36 ft/sec
D) 54 ft/sec
E) 42 ft/sec
