Calculating Angular Velocity and Gear Ratio for a Winding Drum

[ForgottenMemo]

Homework Statement

Homework Equations

w = 2PI f

v = wr

Time = 2PI R/V

The Attempt at a Solution

w = (2000/PI x 60) x 2PI = 66.66 Radians/Sec

V = wr = 66.6 x 300 = 19998 ( Is this velocity of the winding drum)

19998/200 = 99.99 ( Velocity/200 reduction gearbox, gives me the velocity of the motor?)


Help Appriciated.

The centripetal force was also given, but you didn't write down the corresponding formula...
