Using h(t)=gt^2+v0t+h0, where g= 16, h0= initial height, v0= initial velocity, and t= time
A rocket is fired into the air from the top of a building that is 200 feet tall. The initial velocity of the rocket is 600 feet/sec. If necessary, round answers to the nearest hundredth of a unit
a) Write the height function
b) When does the rocket reach its maximum height?
c) What is the rocket's maximum height?
d) When does it hit the ground?

did you sub in the given data into the general formula to get
h(t) = 16t^2 + 600t + 200 ?
for b) and c), find the vertex of the parabola using the method that was taught to you
d) set 16t^2 + 600t + 200 = 0
and solve for t
