Question: a model rocket is launched straight up , with an initial velocity of 1 5 0 m / s . The height of the rocket

a model rocket is launched straight up, with an initial velocity of 150 m/s. The height of the rocket can be modelled by h =-5t^2+150t, where h is the height in meters and t is the elapsed time in seconds. What is the maximum height reached by the rocket?
