A block weighing 82.5 N rests on a plane inclined at 28.8° tothe horizontal. The coefficient of the static and kinetic frictionsare 0.25 and 0.12 respectively. What is the minimum magnitude ofthe force F, parallel to the plane, that will prevent the blockfrom slipping? What is the minimum magnitude of F that will startthe block moving up the plane? What is the magnitude of F isrequired to move the block up the plane at constant velocity?
