Question

If a particle moves along a circular path with a constant speed, i.e., it covers equal distances along the circumference of the circle in equal intervals of time, then its motion is said to be a uniform circular motion. Motion of the tip of the second hand of a clock and motion of a point on the rim of a wheel rotating uniformly are examples of uniform circular motion.\ Calculate the angular speed of a flywheel making 420 revolutions per minute.
