This week we had our mousetrap cars! I have to say this project was a little stressful, but I tried my best.
So basically, you had to make a car, out of a mouse trap, you had to use CD's as the wheels, and you could use string and balloons, basically anything except a rat trap. I made mine with 4 CD's, and the back CD's had a cut balloon around them for traction. Then there was a wooden dowel attached to the mouse trap with a string, that wrapped around the back axle, which was a pen, to make the car move when the trap was set off. The axle was attached with 4 hooks drilled in to the sides of the trap. and then the pens were placed in there. Your car had to go at least 3 meters, and you had to find out the acceleration. so you used the equation Xf= (1/2) a(t)^2 + Vf(t) + Xi.
