How do I find the Velocity and How long will it take for the ball to reach it's maximum height?

Colt1911 [192]

So hmm check the picture below

$\bf \qquad \textit{initial velocity}\\\\
h = -16t^2+v_ot+h_o \qquad \text{in feet}\\
\\ 
\begin{cases}
v_o=\textit{initial velocity of the object}\to &64\\
h_o=\textit{initial height of the object}\to &12\\
h=\textit{height of the object at "t" seconds} \end{cases}\\\\
-----------------------------\\\\$

$\bf \textit{vertex of a parabola}\\ \quad \\

\begin{array}{lccclll}
h(t)=&-16t^2&+64t&+12\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)$

part 1)

it takes $\bf -\cfrac{{{ b}}}{2{{ a}}}\quad seconds$

part 2)

$\bf \textit{now, doubling }v_o\\\\
\begin{cases}
v_o=\textit{initial velocity of the object}\to &128\\
h_o=\textit{initial height of the object}\to &12\\
h=\textit{height of the object at "t" seconds}\end{cases}\\\\
-----------------------------\\\\
\textit{vertex of a parabola}\\ \quad \\

\begin{array}{lccclll}
h(t)=&-16t^2&+128t&+12\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)$

it will reach the maximum height at $\bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\quad feet$

how much higher than before is that? well, what was the y-coordinate for when the vₒ was 64? what did you get for $\bf {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}$ ?

subtract that from this height when vₒ is 128 or doubled, to get their difference, that's how much higher it became

Round 5,762.384 to the nearest ten

swat32

If it's nearest ten then it would be 5,760. If anything is 4 or lower than the number, like 74, then it would be 70.
If it was 5 or higher, like 37, then it would become 40.
Hope this helps! :)
