The equation for a projectile's height versus time is h(t)=-16t^2+Vot+ho A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 110 feet per second. After how many seconds does the ball attain its maximum height? Round to the nearest hundredth.

What are we given in the problem? We are given that our initial height, ho, is equal to 2; alose, we are given the initial velocity, Vo, which is equal to 110 ft/s.

We plug these into the equation, and find the vertex.
