Good job !
x = 6.03 seconds
Step-by-step explanation:
The equation of motion of the rocket is
y = -16x^2 + 193x + 128
We can determine its maximum height ymax when its vertical velocity y' reaches zero. Taking the derivative of y, we get
y' = -32x + 193
The value nen of x that makes y' will give us the time needed by the rocket to reach its maximum height ymax. So setting y' = 0 we get
x = 193/32 = 6.03 second
Bonus:
Putting this value of x into y, we'll get
y(x = 0.59s) = -(16 ft/s^2)(6.03 s)^2 + (193 m/s)(6.03 s) + 128 ft
= 710 ft
