Mass of Projectile - 0.012kg ( 0.02 pounds )

• This was the weight of the clay ball

Horizontal Distance - 5m ( 6 feet )

• This was the distance the projectile had traveled on the x-axis (horizontally)

Time in Air -  .22s

Spring Constant - 214/2 N/M

• This is how resistant to stretching the object was

Initial Spring Constant -  20.74 J

• This would be the energy stored in the stretch of an object

Kinetic Energy of the ball -  3.10 J 

• This would be the energy due to motion

Percent Energy Converted -  15%

• This is the percent of how much PE is converted into KE.

Horizontal Velocity - 22.7 m/s

• This is how fast the projectile traveled horizontally

Vertical Velocity - 1.08 m/s 

• This is how fast the projectile moves upwards

Total Velocity - 22.73 m/s

• This is the total speed which includes the horizontal and vertical components

Vertical Distance - 0.2353m ( 0.7 feet)

• This was how high the projectile goes

Release Angle -  2.72 degrees

• The angle where the projectile leaves the trebuchet and is launched

I think this project went fairly well, everyone got along and put in the equal work. This was our 3rd San Marin STEM project that we have done. This trebuchet was worked on for a few days and the first time we built it, it was okay the first time but when we made the 8 modifications our trebuchet came out better. I worked well in collaborating with others and helping out in my group. Two things I could work on is staying on task and when I notice my team members struggling with work I can help them instead of letting myself get shut out by them.
