On a bobsled run, there is a particularly steep 90° wall. Friction is essential to keep from sliding down this wall. Draw a force diagram to convince yourself that this is true, and explain why. For a bobsled traveling at 26.8 m/s, what is the necessary coefficient of friction to keep it from sliding down the wall? For a wall at 45°, what is the speed at which a 80 kg bobsled plus rider can negotiate a 10 m radius...
