Answer:
Option C is the correct answer.
Step-by-step explanation:
The height, h(t), of the ball can be modeled as a function of time, t, by the equation h(t) = -16t² + 40t + 20
When the ball hits the ground, we have h(t) = 0
h(t) = -16t² + 40t + 20 = 0
Negative time is not possible, so time = 2.93 seconds.
Option C is the correct answer.
