The equation for a projectile's height versus time is h(t)=-16t^2+v^0t+h^o.

A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 120 feet per second. What is the maximum height, in feet, the ball will attain?

Round to the nearest whole foot.
