PLEASE HELP ME PLS ITS MATH

Mathematics
1 answer:
Ganezh [65]1 year ago
7 0

Answer:

9

Step-by-step explanation:

We know that

h(t)=-16t^2+1296

The balls hits the ground when h(t)=0, so

-16t^2 + 1296=0 \\ \\ t^2 - 81=0 \\ \\ t^2 = 81 \\ \\ t=9

Note I only considered the positive case because time must be positive.
