Ch10 Pully with Friction A
The picture below shows a pulley with an axel. There is a force, FT = 20.0N accelerating the pulley. The force of friction between the axle and the pulley is
Ffr = 35.0milliN with an axle radius of 0.7cm. The mass of the pulley is 2.5kg, and it's radius is R0 = 440.0cm.
(a) What is the angular acceleration of the pulley?
(b) What is the acceleration of a point on the edge of the pulley?
Answer all questions to 3SigFigs with units.
