A rocket is launched vertically from the ground with an initial velocity of 64 ft/sec.
diamong [38]

we know the rocket was launched from the ground, meaning its initial height is 0, thus

~~~~~~\textit{initial velocity in feet} \\\\ h(t) = -16t^2+v_ot+h_o \quad \begin{cases} v_o=\textit{initial velocity}&64\\ \qquad \textit{of the object}\\ h_o=\textit{initial height}&0\\ \qquad \textit{of the object}\\ h=\textit{object's height}&\\ \qquad \textit{at "t" seconds} \end{cases} \\\\\\ h(t)=-16t^2+64t+0\implies h(t)=-16t^2+64t

Check the picture below.

A ball travels on a parabolic path in which the height (in feet) is given by the expression $-25t^2+75t+24$, where $t$ is the ti
evablogger [386]

Answer:

The height of the ball is at it's maximum 1.5 units of time after launch.

Step-by-step explanation:

Suppose we have a quadratic function in the following format:

h(t) = at^{2} + bt + c

If t is negative, the maximu value of h(t) will happen at the point

t_{MAX} = -\frac{b}{2a}

In this question:

h(t) = -25t^{2} + 75t + 24

So

a = -25, b = 75, c = 24

Then

t_{MAX} = -\frac{b}{2a} = -\frac{75}{2*(-25)} = 1.5

The height of the ball is at it's maximum 1.5 units of time after launch.
