Simple Friction Experiment
Image:cone.JPG Here you will see a cone fall from a height of 3 metres. You may already have watched this clip and calculated the acceleration of the cone. Now this can be taken a stage further. Given that the mass of the cone is 2 grams, find the magnitude of the resistance force acting on the cone as it falls. You will have to assume that the resistance force is constant and should think about the implications of this assumption.
