Answer:
the ball hit the ground at
Step-by-step explanation:
we have
This is the equation of a vertical parabola open downward
The vertex is a maximum
we know that
The x-intercept of the function is the value of t when the value of h(t) is equal to zero
The ball hit the ground when h(t) is equal to zero
equate the function to zero and solve for t
Factor the leading coefficient
The solutions are
therefore
the ball hit the ground at
