Previous Answers
Correct
Correct answer is shown. Your answer 470.4 N was either rounded differently or used a different number of significant figures than required for this part.
Important: If you use this answer in later parts, use the full unrounded value in your calculations.
To review whether your calculations make sense, let's simplify the problem even further and assume air resistance is negligible. In this case, the net force acting on the bicyclist is equivalent to just the
force of static friction, and your answer to Part D is the magnitude fs. Based on this value, what is the minimum coefficient of static frictions between the race track and the bicycle?
Express your answer numerically to two significant figures.
