-If the radius of the wheel is 38 cm, and the wheel rolls without slipping, how far has the cyclist (in m) traveled in 14 s? X= r * Δ Δ Θ Use this one… change 38cm to m 0.38 m V= r * w a u = r * o X = (0.38 m)(351.86 rad) Δ = 133.71 m -- Another: A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
