View the two videos "bike speed" and "bike cornering" linked at: http://www.kkuykendall.net/videoIndex.htm Answer the following, understanding that you will need to use your common sense in addition to your understanding of physics, and that your answers will be estimates -- on this data I'm comfortable with answers that will differ by +/- 50 %. Make sure you tell me what assumptions and estimates you make and give some sense of the uncertainty you have in these values. 1)How fast are the cyclists going in the first video? 2)What force of friction between bike and road is present when they turn the corner? 3)What is the coefficient of friction between the bicycle tire rubber and road?
