Turtle · Answer 1

120 revolutions per min is (20RPM)

120revolutions is 240 Pi radians (because 1 revolution is 2Pi rad)

angular velocity

w = 240Pixf, f is the frequency and f = 1/T, T = 1mn=60s=period, so f=1/60=0.01Hz

so w = 240*Pi*0.01=12.56 rad / s

linear velocity can be found with

V = Rx w,

V=12.56 R the value depends on what value is the radius of both wheels
