SimpleFreefall

You solved the following problem for homework:

• Suppose you roll a ball off a table that is 1 meter high. If the ball is rolling at a speed of 2 m/s ...
  (a) State any assumptions for the problem and draw a nice diagram, then write down initial conditions and formulae
  (b) When and where will the ball hit the ground?
  (c) Graph the path of the ball. Calculate 10 (x,y) coordinates using your equations--be sure to space out those points at regualr time intervals (the first point should be at the edge of the table, and the 10th should be just as it hits the ground). Show your calculations (Excel is a nice tool to use!).

Now you should work with some teammates to experimentally determine whether or not our freefall equations are accurate. Using a ball, some hotwheels track, our materials testing devices, and a CPO time, recreate the initial conditions for the problem above and compare the actual results to your predictions.

Carefully document your process and results in your notebook (someone should be able to EASILY repeat the experiment based on your lab report & notebook notes). Be sure to record the mass of the ball - you will need this information later.

• Period 2: you have class time on 2/11 and 2/12 to complete your experiment.
• Period 5A: you have 1/2 class on 2/11 and 1/2 class on 2/22 to complete your experiment.

Write a brief lab report and turn it in on time!
