Question

The Demon Drop is a popular ride at the Cedar Point Amusement Park in Ohio. It allows

4 people to get into a little cage and fall freely for a while. Physics professor Bob Speers

of Firelands College in Huron, Ohio took a videotape of the drop. A digital movie with the

file name DSON001 has been made of one of the Demon Drop falls. Use Logger Pro

and EXCEL to analyze and develop a mathematical model (rather than a fit using “Add

Trendline...") that describes the fall. You should use a conventional coordinate system

to express all your vector quantities and vector components in which the positive y-axis

points up. After collecting all your data, place your coordinate system origin so that the

first data point has a value as close as possible to y = 28 m.

Include a printout of your spreadsheet data, graph, and model.

Okay, so I did all of that, and here's my table/model/graph. I just dont understand how to answer this question.

Oh, also, my equasion is y(t)=-69(m/s2)*(t2)-28(m/s)*t+28(m)

So how do I answer this?

1. According to your model, what is the initial position of the cage in conventional vector

notation? Express your vector in terms of the ^x, ^y, or ^z (or ^i, ^j, ^k) unit vectors.

Explanation / Answer

Initial position means y at t=0

This will come as 28.

in vector notation initial position =0i + 28 j

all the best in the course work
