Physics 211 10/8 HW Handout Due Thursday 10/11 Fall 2001 Rotating Drum 1) A drum, rotating once every second, (period T = 1s) has a 0.5kg block inside riding on the wall without slipping down. The block executes uniform circular motion with a radius of 0.75m. a) In the box draw a FBD of the block when it is at the location shown. Include the directions of a and F net . b) Compute the magnitudes of all the forces in you diagram.

Unformatted text preview: Show your work and state which of Newton’s laws you are using. c) If the drum slows down, Which forces on the FBD change? Assume the block still does not slip down the wall. Show your reasoning. d) If the block just starts to slip when the period, T, is 1.2 seconds, what is the coefficient of static friction, μ s between the drum and the wall? Show your reasoning. a = F net =...
