OBJECTIVES:
The goal of the project is to increase your understanding of motion in two dimensions by building a catapult to launch ping-pong balls, and by collecting and analyzing your data.
ASSIGNMENT: Catapults must be brought to school on October 30th 2012! We will launch the ping pong balls on Wed 10/31 and Thu 11/1.
Each team (consisting of three to five students from your class period) must construct a catapult that can launch a ping-pong ball at various angles on a consistent basis. Your team may build a catapult from scratch or use a kit. Your team must be able to measure the launch angle on your catapult.
The catapults on this site came highly recommended:

The catapults must be able to launch the ping pong ball from angles between 15 and 75 degrees. The ping pong ball must cover a range between 1m and 5m.
Catapults cannot exceed 18" X 18" X 18"
PROJECT REPORT - Your report should include:
TITLE
PURPOSE
PROCEDURE: How to collect data. See below for type of data to be collected.
LABELED DIAGRAM OF CATAPULT
DATA COLLECTION: Launce the ping pong ball from the following launch angles 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75. Record the following in your data table: launch angle,- range of flight, - time of flight.
ANALYSIS:Using the data that you have collected determine the following: the initial velocity of the release, initial horizontal and vertical components, the time to the highest point. Show all calculations.
ADDITIONAL REQUIREMENT: You will be given a target to hit on launch day. You will be given the horizontal of the distance of the target on launch day. You will have one try to hit it. You will then calculate the % error of your device.
The title, purpose, and procedure and data table (the table itself; not the actual data) components of your report must be typed. The remaining sections may see hand written.
