Question
A bicycle is rolling down a circular portion of a path; this portion of the path has a radius of 9.47 m. As the drawing illustrates, the angular displacement of the bicycle is? = 0.961 rad. What is the angle (in radians) through which each bicycle wheel (radius = 0.460 m) rotates?
Explanation / Answer
Must subtract angular displacement of bicycle from the calculated angle that each bicycle wheel rotates.
In this case,
19.78 radians - 0.961 radians = 18.82 radians
