Build a Mousetrap Car Using Only a Spring!

AI Thread Summary
For a mousetrap car powered solely by a spring, one effective design involves attaching the spring to a lever arm connected to the axle, allowing the spring's energy to rotate the axle and propel the car. Another option is to use the spring as a compressed coil, releasing its energy rapidly to drive the car forward. Both designs require careful consideration of lever arm length, spring tension, and construction materials to optimize performance. Experimentation may be necessary to achieve the desired speed and distance. These innovative approaches can lead to a successful project outcome.

Alright for my physics class we need to do a mousetrap car... A car that is only powered by the force given out by the spring on a victor mousetrap... You can't use rubber bands or anything like that... Does anyone have any ideas?

The idea of having an arm attached to the spring and pulling it back and wrapping a string around the axel is already taken... So does anyone have an other ideas?

One possible idea for a mousetrap car using only a spring could be to attach the spring to a lever arm, with the other end of the lever arm attached to the axle of the car. As the spring releases its energy, it will push the lever arm and rotate the axle, propelling the car forward. This design may require some trial and error to find the right balance of lever arm length and spring tension to achieve the desired distance and speed. Another option could be to use the spring as a compressed coil to provide a burst of energy to the car, similar to how a compressed air-powered car works. This would involve creating a mechanism to release the spring's energy quickly and efficiently. Whichever design you choose, be sure to carefully consider the materials and construction to ensure the car is both safe and effective. Good luck with your project!
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
