f= (17.85) / (1.671)
f= 10.682 N
efficiency = (energy out / energy in) * 100%

Reflection
Ashar -On launch day, our catapult barely managed to hit one of the three targets that were set. This is mostly due to the fact that we spent too much time planning and not enough time working on the catapult which resulted in our catpult only hitting one of the targets. Another reason for the catapult nt hitting the targets is that only one person was given the responsibility to build the catapult, if more than one person worked on building than we would have saved a lot of time. In future projects, we plan on managing our time wisely and also checking to make sure how many people are needed for a specific task.
Mehali - We may of taken too much time on the planning instead of the construction. We only began building the catapult a week before the launch, and only 2 days to test. As a result, our targets and distances were not as accurate and as far as I would of liked. Next time, we should plan our time so that it is equally spent on planning and construction, with enough time leftover to test.
Navreek- I enjoyed launching the catapult. It was a fun project for me because I like building things and testing them out. We could've done better if the project was started a bit early. By doing so, we could've tested it before hand and maybe able to hit more targets.
NEXT YEAR'S CLASS: DONT USE BUNGEE CORDS
