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 $h ( t ) = - 4.9 t ^ { 2 } + 61 t + 4$ 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) 237 m
B) 4 m
C) 6 m
D) 194 m

Solve the Problem h(t)=−4.9t2+61t+4h ( t ) = - 4.9 t ^ { 2 } + 61 t + 4h(t)=−4.9t2+61t+4

Solve the Problem $h ( t ) = - 4.9 t ^ { 2 } + 61 t + 4$
