An object is launched vertically in the air at meters per second from a -meter-tall platform. Using the projectile motion model where h(t) is the height of the projectile t seconds after its departure, is the initial velocity in meters per second, and is the initial height in meters, determine how long it will take for the object to reach its maximum height. What is the maximum height?.
