Answer:
A. 2.03
Step-by-step explanation:
Formula.
When h(t) = 0 means that the ball is on the ground.
So, we equal the equation to 0, and then we clear t to find it.
To solve t we have to use the quadratic formula.
a = -4.9
b = 6
c = 8
Then x2
x2 It is not possible because time cannot be negative.
