Question

the height of a projectile is modeled by h(t) = -16t² + 64t + 80. what does the zero at t = 5 mean in this context? (1 point) the projectile starts moving the projectile changes direction the projectile reaches maximum height the projectile returns to ground level at 5 seconds

Explanation:

The function $h(t)$ represents the height of the projectile at time $t$. When $h(t)=0$, it means the height of the projectile is zero, which is the ground - level. Since there is a zero at $t = 5$, it implies that at $t=5$ seconds, the height of the projectile is zero, i.e., it returns to the ground level.

Answer:

The projectile returns to ground level at 5 seconds
