b. Draw a table. You will use this table to record your data. Here is an example:
Coaster Car - Mass #1
Coaster Car - Mass #2
Coaster Car - Mass #3
Coaster Car - Mass #4
c. Determine the mass of your 4 different coaster car configurations and record
your data in the table.
d. Predict which coaster car configuration will need to be released at the highest
level on the tower in order to make it through the loop, then predict which
will be the next highest, etc. until all the coaster car configurations are ranked
in some order.
3. To test your predictions, you should:
a. Determine the minimum height of release which allows a coaster car
configuration to just pass through the loop. Once you have determined
the appropriate position on the track, mark it with a piece of masking tape
and measure the height of the tape above the surface on which the coaster
stands. Record your data in the table.
b. Remove the masking tape and repeat the measurement for the other 3
coaster car configurations.
4. Analyze your data:
a. Were all of the heights attained the same? Different? Explain.
