The circumference of a bicycle wheel is 2 meters. If it rotates at 2 revolutions per
second then its linear speed is approximately
[v-rw where means approximate, v is linear speed, r is meters from axis and wis
rotational speed.
That is, linear speed is approximately distance from axis, times, rotational speed.]

a. 1 m/s.
b. 4 m/s.
c. 3.14 m/s.
d. 6.28 m/s.
e. 3 m/s.
