List of items Marble Funnel Cardboard box Duct tape Clear plastic tubing Hot wheels track with loop Mousetrap String A screw Small plank of wood Fabric Bowling ball

Summary Box gets bumped causing the ball to fall into funnel Ball follows track to the mousetrap Lands on the mousetrap setting it off A string attached to a screw on one end, is pulled by the mousetrap from the other end The screw is pulled out from under the wood The bowling ball rolls down the wood revealing the banner

Equations mmgh =.5mv^2 +.5I ᾠ ^2 TT = F * r * sin(Ө) RR = (mr + mr +... mr)/(m + m +... m ) DDy = vy0(t) +.5(a)(t^2) DDx = vx0(t)

Problems We had some problems finding the right size ball to fit in the tubing. Once set up it took multiple runs to find the right placement of mousetrap. When the ball hit the mousetrap we lost it frequently because it was flung out of our sight. Since we used the cheap mousetraps they kept breaking on us after 2 or 3 runs.

Conclusions WWhile constructing our project our goal was to spend the least amount of money but still have a quality project meeting all requirements. BBeing able to apply the concepts learned in class as a group makes engineering so much more engaging than doing written work by yourself.
