Bull’s Eye!
Goal
To make the marble land in the bull’s eye when released from the ramp on the computer desk.
Materials
aluminum ramp, marble, meterstick, DO NOT USE A STOPWATCH!!
Procedure
All of the information that you collect depends on the release point of the ball and the ramp you use.
Be sure you keep this constant.
1. At your lab table roll the marble down the ramp. What information can you measure or
collect from the roll? (Δd, vi, vf, a, t? horizontal and vertical?) (NOTE: You’re using the data
for when the ball is in the air, not when you drop it down the ramp. Initial velocity should be
for the moment when it leaves the ramp.)
2. Release the ball and collect the information you indicated above so that you can predict where
the ball lands on the ground from your table and complete the following table.

3. Your goal is to roll the ball from the ramp at the front table and get it to land in the bull’s eye.
You get only one try. Use your data from above to predict the distance the ball will travel.
The instructor will mark whether you hit the bull’s eye or not.
4. List the differences between the rolls at your lab table and the test at the front table.
5. Calculate the distance you plan to set the bull’s eye from the edge of the front table.
We will set the bull’s eye ________________meters from the edge of the table.
