A washing machine works by rotating the drum about a horizontal axis in a vertical plane. For thorough cleaning, detergent is sprayed from tiny holes in the surface of the drum.
Determine the minimum speed v for which the drum has to spin to ensure the clothes remain in contact with the drum for maximum detergent absorption. Treat the clothes as a single particle with mass, m = . The effective radius of the drum is r = . Assume the clothes do not slip relative to the drum anywhere along the circular motion.
Please enter in a numeric value in m/s.
