Build a Catapult to Shoot a Ball 2m into a Bucket

[ConsistentX]

we were given a project in physics where you build a catapult that shoots a tennis ball 2, 4, or 6m. Now i have a basic design that I am not sure if it will shoot 2m. all i need is the ball to be able to shoot 2m into a 5 gallon bucket.
here is the design i am loooking at:

Also. if i decrease the stopping point of the catapult will that increase the distance?

Does it have to be a catapult, or can it be a trebuchet? Trebuchet's are much easier to build, generally.

Thank you for sharing your project in physics. Building a catapult to shoot a ball 2m into a bucket is a great way to apply concepts of projectile motion and energy transfer. Your basic design is a good starting point, but it is important to consider a few factors to ensure that the catapult will shoot the ball 2m into the bucket consistently.

Firstly, the distance the catapult shoots the ball depends on the initial velocity of the ball, which is determined by the tension in the rubber bands and the angle of the catapult arm. To achieve a consistent 2m distance, you may need to adjust the tension in the rubber bands or the angle of the arm. You can also experiment with different types of rubber bands to see which ones provide the best tension for your desired distance.

Secondly, the stopping point of the catapult will affect the distance the ball travels. Decreasing the stopping point will increase the distance, but it is important to find the right balance so that the ball does not overshoot the bucket. You may need to do some trial and error to find the optimal stopping point for a 2m distance.

Lastly, it is important to consider the accuracy and precision of the catapult. A consistent 2m distance is great, but if the ball is not landing in the bucket consistently, then it may not be a reliable design. You can test the accuracy and precision of the catapult by shooting the ball multiple times and measuring the distance and location of each shot.

Overall, your design is a good starting point, but it may require some adjustments and testing to achieve a consistent 2m distance. I encourage you to continue experimenting and making improvements to your catapult. Good luck with your project!
