Homework Statement
A bicycle is rolling down a circular portion of a path; this portion of the path has a radius of 7.78 m. As the drawing illustrates, the angular displacement of the bicycle is 0.877 rad. What is the angle (in radians) through which each bicycle wheel (radius = 0.330 m) rotates?
Homework Equations
The Attempt at a Solution
Basically, what I did to solve the problem was that I multiplied the angular displacement
of the bicycle and the radius of the path. So it was 0.877 x 7.78 and I got 6.82306. To
this number, I divided 0.330, which is angle of bicycle wheel and I finally got 20.7, but
the website says that this is wrong. I tried to put 20.68 and it was still wrong. Can someone
tell me if I did something wrong to do this problem? The unit must be in radians. Thanks.
