Then the speed of the rider is, v = 2m/s
The linear velocity of an object in a straight line is its speed.
The following is the relationship between linear and angular velocity:
v = rω
The circumference of the bicycle wheel is,
2r = 2
r = 0.318m
The angular velocity of the wheel is,
ω = 1rev/sec = 2rad/s
Then the speed of the rider is,
v = rω
v = 0.318×2π
v = 2m/s
