a bicycle has a wheel of radius of 35.56cm.what is the angular speed of the wheels when the bicycle has a forward speed of 8.0m\s?
We can start by using the formula:
v = rω
where:
v = linear speed or velocity (in m/s)
r = radius of the wheel (in meters)
ω = angular speed or velocity (in radians/s)
First, let's convert the radius of the wheel to meters:
r = 35.56 cm = 0.3556 m
Next, we can plug in the given values and solve for ω:
v = 8.0 m/s
r = 0.3556 m
v = rω
ω = v/r
ω = (8.0 m/s)/(0.3556 m)
ω = 22.5 rad/s
Therefore, the angular speed of the wheels is 22.5 radians/s.
