1. Engineering Final Team Project Drew Jones, Rob Hellmann, Corey Woodward, Verity Yata

2. The Bruce Pearl Machine Our Rube-Goldberg contraption uses a series of actions to complete a ball flying through a basketball hoop

3. First a weighted club is released and collides with a golf ball Next, the golf ball rolls along the box and hits the tennis ball. Then, the tennis ball rolls off the box and hits the spoon Finally, the spoon launches the nerf ball through the hoop.

4. Calculations Potential Energy of the club using mgh=1/2mv² Impulse from the collision between the club and the golf ball using v gb =(m c v c )/m gb Impulse from the collision between the golf ball and the tennis ball using v tb =(m gb v gb )/m tb Velocity of the tennis ball when it hits the spoon using mgh=1/2mv 2 Velocity of release of the nerf ball using projectile motion

5. Calculations Velocity of club when it hits the ball V=1.638 ft/s Velocity of golf ball after club hits it V=14.56 ft/s Velocity of tennis ball after golf ball hits it V=10.92 ft/s Velocity of tennis ball when it falls off the block V=5.433 ft/s Velocity of release of nerf ball V=1.30 ft/s

6. Masses Weighted stick: 400 grams Tennis ball: 60 grams Nerf ball: 5 grams Spoon: 5 grams Golf ball:45 grams

7. Approximate costs Swinging mass and structure with duct tape- $8 Nerf ball and basketball goal- $5 Two boxes- $1 Golf ball- $1 Tennis ball- $1 Spoon- $1 Violet block (fulcrum)- $1 Total Costs- $18
