A string is wrapped around a uniform cylinder of radius R and mass M that rests on
Question:
A string is wrapped around a uniform cylinder of radius R and mass M that rests on a horizontal frictionless surface. The string is pulled horizontally from the top with force F.
(a) Show that the angular acceleration of the cylinder is twice that needed for rolling without slipping, so that the bottom point on the cylinder slides backward against the table.
(b) Find the magnitude and direction of the frictional force between the table and cylinder needed for the cylinder to roll without slipping. What is the acceleration of the cylinder in this case?
Step by Step Answer:
a The only force is F therefore a cm FM The torque about ...View the full answer
