a flywheel makes300.rpm. find the angular speed of any point on the wheel and the linear speed(tangential) of a point 5.00m from the center.
V = 300rev/min * 6.28rad/rev * 1min/60s
= 31.4 rad/s.
Circumference = pi*2r = 3.14 * 10=31.4 m.
V = 300rev/min * 31.4m/rev * 1min/60s =
157 m/s. = Linear speed.
