The school physics class has built a trebuchet (catapult) that is big enough to launch a watermelon. The math class has created the function h(t) =-16(t - 4)2 + 320 to model the height, in feet, after t seconds, of a watermelon launched into the air from a hilltop near the school. (The projectile of the watermelon is aimed towards an empty field that is on
the school campus.)

Find the standard form of h(t) and use it to reveal the y-intercept. Explain the meaning of the y-intercept in this
context.
