A wheel with a radius 10 inches covers a distance of 40pie inches in one second. What is the angular speed of this wheel?
2 answers:
Angular velocity is given by: ω=v/r where: ω=angular velocity v=linear velocity r=radius From the question; v=40π inches/sec r=10 therefore: ω=40π/10= 4π radians per per/sec
Answer: B)
Step-by-step explanation:
Since, the wheel covers a distance of inches in one second.
Thus, its linear velocity =
Also, the radius of wheel = 10 inches,
Hence its angular velocity =
⇒ Option B is correct.
