Sergio launches a projectile from the top of a 50- foot high building. The initial velocity of the projectile is 32 feet per second. The height of the projectile is modeled by the function h(t)=−16t^2+32t+50 , where t is measured in seconds since the launch.

What is the maximum height the projectile reaches?
