Answer:
Step-by-step explanation:
Because the velocity is in feet per second, we will change the circumference of the wheel to feet as well.
C = πd so
C = 3.1415(28)
C = 87.9646 inches *
= 7.3304 ft in 1 revolution
Angular velocity is
ω =
where r is the radius of the wheel. We know that this wheel travels 7.3304 in 1 revolution, and 1 revolution is equal to 2pi, so
ω =
. That's how fast the angle of the wheel is changing.
As far as the rotations or revolutions per second goes,
