Have you ever calculated the velocity of a rollercoaster you rode? The odds are that the rush of the rollercoaster left you unable to do so. So nows your chance

This rollercoaster went from 0-135 mph in 3.15 seconds

The equations you can use are

\begin{align*}v =\end{align*}

\begin{align*}v_i =\end{align*}

\begin{align*}v_f =\end{align*}

\begin{align*}\Delta v =\end{align*}

\begin{align*}v_{avg} = \frac{\Delta x}{\Delta t}\end{align*}

\begin{align*}a =\end{align*}

\begin{align*}a_{avg} = \frac{\Delta v}{\Delta t}\end{align*}

First we must find convert mph to m/s

\begin{align*}\Delta v =\end{align*}

so (60.44/3.15)=19.16m/s

Therefore the average velocity is 19.16

Creative Questioning:

1. How would you change the outcome of this question?(which factor would you have to change?

2.What is the relation between velocity and time?
