A bicycle is rolling down a circular portion of a path; this portion of the path

Question

A bicycle is rolling down a circular portion of a path; this portion of the path has a radius of 9.96 m. As the drawing illustrates, the angular displacement of the bicycle is 1.250 rad. What is the angle (in radians) through which each bicycle wheel (radius = 0.400 m) rotates?

A bicycle is rolling down a circular portion of a path; this portion of the path has a radius of 9.96 m. As the drawing illustrates, the angular displacement of the bicycle 1.250 rad. What is the angle (in radians) through which each bicycle wheel (radius = 0.400 m) rotates? radians the tolerance is +/-2%

Explanation / Answer

1.25*9.96 = n*2*pi*0.4

n =1.25*9.96/(2*pi*0.4

n =4.95

therefore angle rotated = 4.95 *2pi = 31.125 rad
