Homework Statement
A bicycle with 0.8 m diameter tires is coasting on a level road at 5.6 m/s. A small dot has been painted on the rear tire. What is:
a) the angular speed of the tire
b) the speed of the dot when it is 0.8 m above the road in m/s?
c) the speed of the dot when it is 0.4 m above the road in m/s?
The Attempt at a Solution
a)
ω=v/r
ω=5.6/0.4
ω=14
for (b) and (c), can someone help me understand why the answer is not 5.6 m/s for both of them?
