Solve the problem.
A fireworks mortar is launched straight upward from a pool deck platform 4 m off
the ground at an initial velocity of 61 m/sec. The height of the mortar can be
modeled by h(t) = 4.97 +61t+4, where h(t) is the height in meters and t is the time in
seconds after launch. What is the maximum height? Round to the nearest meter.
A) 194 m
OB) 237 m
C) 4 m
D) 6 m
